 I believe I've figured out why 
I'm getting those:

globus_mutex_lock() failed; errno 6
globus_mutex_lock() failed; errno 6

errors. The mutex in question, internalMutex, is NULL. It appears that 
it's never getting initialized. It looks like the function that was 
designed to do this is globus_l_thread_activate() (line 51). After 
setting break points on that function, it appears that it never gets 
called. I added a line to globus_mutex_lock that calls 
globus_l_thread_activate() if the mutex pointed to by mut is null. That 
seems to fix the problem, though you might have a better solution.
