I have an application which needs to communicate to X (which it does through
XtMainLoop) and another independent process.  Currently, we are doing this
by polling first X and then the other process.  This busy-wait has been
identified as a performance bottleneck in our system, however, and we would
like to remove it.  

Is there any way of integrating non-X events into the X event mechanism,
either through Xlib or the toolkit?  Ideally, we would like to be able to
have something like XtAddEventHandler--that is, we would like to be able to
say, upon seeing event A, call routine B.  

Any ideas?  My apologies if this has been discussed already.

Thanks.  rick
