having read david's response, i must obviously ammend my previous post:
1) my change to highlight the functionality is indeed missing the
opportunity for the mainloop to do anything; code modified to
explicitly have the mainloop do the work of posting the messages.
2) as has been discussed, gtk_events_pending() is not good gtk form,
avoid it unless absoutely unable to.
3) and, the sleep() is intended only to illustrate, do not write such
blocks in a GUI, this too is bad form, the user will get quickly
frustrated and curse your name often.
