I can't help much with your quest for a debugger, but I have a small
hint. By far the most common cause of mysterious CORBA deadlocks with
call-backs is forgetting to activate the POA on the client side. That
causes the calls to block waiting for POA activation.

To find genuine deadlocks, I normally resort to attaching to the
Python process with gdb, and looking at the C stack traces. That's
often enough to get an idea of which thread is trying to do what.

Cheers,

Duncan.
