sideline thread has no chance to clean up

From derek.br...@gmail.com on April 23, 2010 14:49:38

In debug build DR synchs + terminates our sideline thread prior to calling our exit event so we have no chance to clean up its memory. DR then asserts about leaks if the sideline thread had thread-local memory. DR either needs to call the client exit event even sooner, before the synchall, or should add support for a sideline exit routine.
