I don't know much about the internals of the X server, but doesn't it 
need to keep track of clients so that when they are killed memory and 
other resources are released?  Why would the screensaver suspend be any 
different.  IMO, the app should call XScreenSaverSuspend(True) *once* 
(not 30 frames per second).  And then either call 
XScreenSaverSuspend(False) when it is done, or simply exit and let X 
clean up.
