Ahh. A quick Google search suggests that yes, freeglut is not aware of threads.
In that case, it sounds like you need to either make sure that all your glut
calls are from the same thread, or use a mutex to ensure that you only call
glut from one thread at a time.

Assuming that's actually your problem, I'm marking the bug resolved. If you
find evidence that this really is an X bug, feel free to reopen this.
