This class creates core-local caches for a given shared_ptr, to mitigate contention when acquiring/releasing it.

class CoreCachedSharedPtr;It has the same thread-safety guarantees as shared_ptr: it is safe to concurrently call get(), but reset()s must be synchronized with reads and other reset()s.
