Detailed Description

Manages the lifetime of CallEvent objects.

CallEventManager provides a way to create arbitrary CallEvents "on the stack" as if they were value objects by keeping a cache of CallEvent-sized memory blocks. The CallEvents created by CallEventManager are only valid for the lifetime of the OwnedCallEvent that holds them; right now these objects cannot be copied and ownership cannot be transferred.
