If someone were choosing an ORB, they perhaps could look at whatever the
Gnome project chose (either mico or ORBit, can't remember which). Also,
they didn't consider ILU because of licensing considerations, but the
license changed very recently and I think would now be a strong
candidate...

The PG backend is neither reentrant nor threadsafe, and isn't likely to
become so soon (several/many places where global variables are used,
etc).

However, with the existing "forked model", there is a separate backend
for each client, so (if I understand things a bit) the trick will be
figuring out how to call a single routine which will give access to a
client (as happens now) but without handing off through a socket/IP
connection.
