       Is it possible to have a graphics process create child processes that
    are still allowed to render to the parent process's graphics window?

       A possible scenario would be something like this:  The main graphics
    program would fork a process to monitor some device so as
    not to keep the main process all tied up with the little book-keeping 
    tasks.  But at the same time, it would be nice if the child process could
    update its information on the main process's window where all the status 
    information would be kept/displayed.  The problem I forsee in this is
    the event queue (mainly) and the matrix stack for that specific window.

       Any hints/past experiences would be appreciated.

                                              Thanks,
