This test needs to have a require for the Listen gem or else it returns
an error when run by itself or with a certain order in the Active
Support tests. We use `silence_warnings` because Listen has some
warnings about private methods. It's already silenced when it's required
in Active Support EventedFileUpdateChecker.
```

accessors"
This reverts commit 301f43820562c6a70dffe30f4227ff0751f47d4f per @matthewd on https://github.com/rails/rails/pull/22630/files#r47997074

We call the thread variable accessors on `Thread.current`, which matches Ruby's
documentation:
http://ruby-doc.org/core-2.2.0/Thread.html#method-i-thread_variable_get
Fix these to stay `current` ( ͡° ͜ʖ ͡°)

When setting the Rails logger to log to STDOUT, it would broadcast the
log twice in development. This adds a setting that will prevent messages
from being broadcast to multiple logs, while still allowing calls to
`#close`, `#level=`, `#progname=`, and `#formatter=` to be broadcasted.
Fixes #14769, #11415

Before this commit, the sole presence of the Listen constant
enabled the evented file watcher (unless listen resorted to
the polling backend).
This way, applications may depend on listen for other stuff
independently of this feature. Also, allows teams with mixed
setups to decide at boot time whether the evented watcher
should be enabled for each particular instance.

Corrects the time comparison to be `Time.now < time` which allows the user to
be set only when the current time is less than the 2 week window given in the
example.

[ci skip] Add a dollar sign to each command in the READMEs

| | | |

According to pr #22443 in the guides there's always a dollar sign before every command, so why is in the main README a `$` and in every submodule a `%`?
Just eye candy..

Subscribing to notifications while inside the said instrumented section

The issue is that on the exit from Instrumenter#instrument section,
an Evented listener will run into an error because its thread local
(Thread.current[:_timestack]) has not been set up by the #start
method (this obviously happens because the Evented listeners didn't
exist at the time, since no subscribtion to that section was made yet).
Note: support for subscribing to instrumented sections, while being
inside those instrumented sections, might be removed in the future.
Maybe fixes #21873.

The failure have returned, so disabling the tests again. (The upgrade is

In listen 3.0.4 and below, the `#stop` method on the notification
backends are a no-op, meaning that we are leaking them per test. This
ended up triggering another bug in Ruby that causes our builds to fail
randomly on CI.

There is a known issue with the listen tests that casuses files to be
incorrectly GC'ed even when they are still in-use. The current is to
only run them in isolation to avoid randomly failing our test suite.

Fixes #22376.
JRuby 9.0.5.0 will support ObjectSpace.each_object against a
class's singleton class, since that's essentially just walking an
internal subclasses structure we already maintain. This test was
too narrow, requiring that each_object support an arbitrary class
but only actually needing it to work against a class's singleton.
This improves performance of Class.descendants by nearly two orders
of magnitude when run against JRuby 9.0.5.0:
```ruby
5.times { puts Benchmark.measure { 100_000.times { Numeric.descendants } } }
```

This method needs to ensure that if a change happens, it is going to be registered.
With this refactor suggested by @matthewd race conditions do not matter because if
no file is watched, nothing is done. And as long as some invocation sets the flag
to true, it will stay true.
The refactor leaves a race condition in which two simultaneous threads that watch
some of the files passed do the actual work in `any?`, whereas the mutex guaranteed
that was done at most once. But this is considered to be a better tradeoff.

Not only does this make for simpler, more obvious code, it's also more performant:
require 'benchmark/ips'
module Enumerable
def old_sum(identity = 0, &block)
if block_given?
map(&block).old_sum(identity)
else
inject { |sum, element| sum + element } || identity
end
end
def new_sum(identity = 0, &block)
if block_given?
map(&block).new_sum(identity)
else
inject(:+) || identity
end
end
end
summable = (1..100).to_a # sum is 5050
Benchmark.ips do |x|
x.report("old_sum") { summable.old_sum }
x.report("new_sum") { summable.new_sum }
x.compare!
end
# Calculating -------------------------------------
# old_sum 10.674k i/100ms
# new_sum 14.542k i/100ms
# -------------------------------------------------
# old_sum 117.350k (± 7.1%) i/s - 587.070k
# new_sum 154.712k (± 3.8%) i/s - 785.268k
#
# Comparison:
# new_sum: 154712.1 i/s
# old_sum: 117350.0 i/s - 1.32x slower
More benchmarks [here](https://gist.github.com/tjschuck/b3fe4e8c812712376648), including summing strings and passing blocks. The performance gains are less for those, but this version still always wins.
