No, but we have used GNAT and VADS (SunSoft Ada). You will likely find
that your out-of-the-box X11R6 hasn't been built with thread
awareness; see XInitThreads(3), XtToolkitThreadInitialize(3). In that
case, you must make sure that each of your Displays is only accessed
by one task. I don't think it would be safe to provide your own
serialization, since your widgets are relying on X events being
dispatched to them and the X events (eg Button1Down) are not under
your control.

NB, you can have more than one Display connection to the same server ..
