libX11 and thread-safety

Has anyone else experienced thread safety problems with libX11?

Specifically, I'm finding that some threaded apps that use libX11 are 
getting hung up on the ConditionWait() in _XReply().

The apps are calling XInitThreads() as they should.

I tried commenting-out the ConditionWait() and that seemed to solve my 
problem.  Of course, that's not a proper fix.

Just wondering if anyone else has come across anything like this or 
has any ideas.
