[Orbit-python-list] non-blocking patch

[Adam O. <rh...@d2...>]

Attached is a simple patch which adds an iterate() function, which is
like run() only it returns immedietly instead of blocking. :)

It works with my very limited testing (while 1: orb.iterate()), but
like shutdown(), it doesn't bother to check that the orb is actually
running, and can cause segfaults because it is.  It'd be very nice if
it threw an exception, since that'd allow you to do:
try:
    while 1:
        orb.iterate()
except:
    pass

which'd act the same as simply calling orb.run().  except it doesn't
sleep of course :)

Could you provide an example usage of this feature?

I am unfamiliar with the mainloop in glib and orbit, so i dont feel
comfortable to comment. However, I do know that the signal handler there
is going to cause problems.

Also, you reported that orb.shutdown() is going to cause segfaults. It
would be nice to avoid that as well; your idea for a global check sounds
good. Tack?

Take care,

I spoke too soon.  Attempting to use a callback deadlocks. :(
(I'm attaching my code incase someone else has a clue.)

Have you tried not sleeping? Alas, that is the problem with mainiteration
lacking I think.
