Instead of sleeping, use a timer.
If that's a pain, perhaps you can have code like
    while (gtk_events_pending()) {
        gtk_main_iteration();
	if (weWaitedLongEnough) {
	    break;
	}
    }
and have a timer set the weWaitedLongEnough variable.

Or, check with gettimeofday() each time round the loop, but that's
slightly slower and probably less portable to non-Unix systems.

It all depends on why you are using the sleep.
