5502	race condition between shared_mutex timed_lock and lock_shared	eliothorowitz@…	viboes	"There is a potential race condition between 3 threads.
Thread 1 - has a shared lock
Thread 2 - goes into a timed_lock loop with a small sleep
Thread 3 - tries shared_lock

Expected behavior:  Thread 3 gets the lock when thread 2 fails to get exclusive lock.

What happens: based on timing, there can be a race condition causing a hang unless Thread 1 releases the lock.

Test and patch for boost-trunk that fixes the problem for me attached."	Patches	closed	Boost 1.49.0	thread	Boost Release Branch	Showstopper	fixed		eliot@… viboes
