Hello,

I had *limited* experience with X while developing a simulation package for the
time-domain response of a control system; what I have seen so far  about  X  is
very  exciting  and  the  notion of a network transparent window system will be
highly desirable in the project I am about to begin.  Given all that:

   - What mechanism does the X server use to handle events?

   - Can this mechanism be accessed to porvide  the  functionality  to  do
     things such as priority-based preemptive scheduling tasks.

   - If  the  X  server can't be used directly in a real-time application,
     can I still work around its limitations and sort  of  take  over  the
     handling  of  time-critical events, by programming say at Xlib level,
     in an efficient manner?

Thanks in advance for your comments and suggestions.
