No, I don't think it is a problem, there's no gl magic in a thread.  
Just make sure your threads acquire a lock before calling any  
(section of) gl* commands to mutually exclude them from accessing the  
OpenGL engine.

Note however that depending on the structure of your code this may  
actually decrease performance, each thread always waiting on the  
other. Designating a thread for gl commands is certainly a simpler  
and cleaner solution.

Best,
