    This may cause problems, since I believe that GLX uses the X wire
    protocol, leading to an Xlib async error.

    You might want to look into a multithreaded application. X11R6 has
    some support for multithreaded applications. I'm not sure how smart
    OpenGL is about multithreading, though.
