Removing this feature causes boost in performance when using Ruby 1.9.
Ruby 1.9 started to do implicit conversions using `to_ary` and `to_str`
in some STDLIB methods (like Array#join). To do such implicit conversions,
Ruby 1.9 always dispatches the method and rescues the NoMethodError exception
in case one is raised.
Therefore, since the whiners feature defined NilClass#method_missing, such
implicit conversions for nil became much, much slower. In fact, just defining
NilClass#method_missing (even without the whiners feature) already causes a
massive slow down. Here is a snippet that shows such slow down:
require "benchmark"
Benchmark.realtime { 1_000.times { [nil,nil,nil].join } }
class NilClass
def method_missing(*args)
raise NoMethodError
end
end
Benchmark.realtime { 1_000.times { [nil,nil,nil].join } }

as different ruby implementations may have different values,
for example Rubinius returns 53 for nil.id.

add lazy_load_hooks.rb, which allows us to declare code that
should be run at some later time. For instance, this allows
us to defer requiring ActiveRecord::Base at boot time purely
to apply configuration. Instead, we register a hook that should
apply configuration once ActiveRecord::Base is loaded.
With these changes, brings down total boot time of a
new app to 300ms in production and 400ms in dev.
