Ah, this is *very* useful information, it'll undoubtedly save me a lot
of work in the future.

But: I don't think this is the problem right now, at least, if I read
your message correctly (only call RNE in the thread that loaded
Carbon). First, Python isn't multithreaded internally, so if you don't
start threads there's only the main thread. Second, Tony reported that
a standalone
    cc tkMacOSXAppInit.c -o a.out
exhibited the same problems.

So, if it's not the .app that is the problem there is something else
that needs to be done before you can use events, and that both Python
and this simple test program don't do.
