res_sorcery_memory_cache.c: Shutdown in a less crash potential order.

Basically you should shutdown in the opposite order of how you setup since
later setup pieces likely depend on earlier setup pieces.  e.g.,
Registering your external API with the rest of the system should be the
last thing setup and the first thing unregistered during shutdown.
