actually, that might be a little different. linking against pthread changes 
the entire "look" of the process. for one thing, any threaded application on 
linux automatically has 3 threads (initial, manager, and main - i think). for 
another, pthread does some nice things like setting up TLS for some globally 
accessed data members (like errno).

its quite possible that something in the non-mt-tq lib reacts badly to that. 
when did it crash? startup, shutdown? thats where most big problems come from 
combining threaded and non-threaded systems.

in general, though this is correct. you should be able to link a threaded 
application with a non-thread aware library and not have any problems.
