*	We need stricter locking before we can unload	Matthew Draper	2015-07-20	1	-5/+11
\| \| \| \| \| \| \| \| \| \| \| \|	Specifically, the "loose upgrades" behaviour that allows us to obtain an exclusive right to load things while other requests are in progress (but waiting on the exclusive lock for themselves) prevents us from treating load & unload interchangeably: new things appearing is fine, but they do not expect previously-present constants to vanish. We can still use loose upgrades for unloading -- once someone has decided to unload, they don't really care if someone else gets there first -- it just needs to be tracked separately.
*	Document ShareLock and the Interlock	Matthew Draper	2015-07-09	1	-6/+2

*	Rely on the load interlock for non-caching reloads, too	Matthew Draper	2015-07-09	1	-0/+10

*	Soften the lock requirements when eager_load is disabled	Matthew Draper	2015-07-09	1	-0/+35
	We don't need to fully disable concurrent requests: just ensure that loads are performed in isolation.
