   I don't see how they help.  The problem is that the X-server
is in a situation where it has to wait for something to complete
before it can continue, and it knows that it will take a long time 
before that something will complete.   All it can do now is burn the
CPU during that time.

   I'm assuming futexes are some interprocess mutex mechanism?
If so, I don't see how this helps.


                        Mark.
