Well, Alan Cox used it for Gnoom, and it apparently works
OK with that. There might be a need for an actual non-blocking
main loop (somebody made a start of it with gtk_main_iteration_do()
but that doesn't work now). However, the only thing that would save,
as far as I can see, would be a single call to XPending() for
each event read from the queue. 

Functionally, the above should work the same. You can also make
sure that gtk_main_iteration doesn't block by setting up an
empty idle handler.

I don't think this is relevant for an ORB in any case. It should
_not_ be sitting on the CPU like that.
