The bug is now fixed in CVS and the bugfixes patch. It will appear in
tonight's snapshot too. The problem was a deadlock between the Python
interpreter lock and an internal lock in omniORB. The fix is to be
more careful about unlocking the Python lock before calling into
certain ORB functions.

I'm surprised that you see 1.2 being slower than 1.0. Nothing has
changed which should affect performance in any significant way, and I
haven't seen any change. What are you doing which is much slower in
1.2 than in 1.0?

I don't recommend using 1.0, since there are quite a few bugs which
have been fixed since then.

Cheers,

Duncan.
