I'm missing something here. XtAppMainLoop never returns to the caller.
How exactly are you planning on getting the sockets serviced? Are you
saying that you hooked a socket servicing routine into an X event
somehow? If so, exacty how?

Have you tried doing this exact same thing in C-only code? Sometimes I
find it useful to remove that particular variable when I'm trying to
test something new.
