If you have a look at the MIT Xt manual you will notice it states that
XtMainLoop() is a trivial procedure. It's of the form:

void
XtMainLoop()
{
	XEvent	ev;

	while (1) {
		XtNextEvent(&ev);
		XtDispatchEvent(&ev);
	}
}

You can implement your own variation of the above to, say, check for a
global flag each time round the loop and taking appropriate action if set.
