bullet3/examples/SharedMemory/PhysicsServerCommandProcessor.cpp
erwincoumans 04d03d10be Fix memory leak due to batchRayCast never deleting the btTaskScheduler. 
(and issue with TaskScheduler/btTaskScheduler.cpp, add JobQueue::exit, call it first, since it uses the m_threadSupport which was deleted before the destrucor was called.
Use a hashmap to store user timers, to avoid allocating many identical strings.
