Paul,

I think the problem here is that omniORB follows a "thread per
connection"
model on the server side, meaning that the same server thread is
handling
all up calls from the same client.  There is probably a way to
instrument
omniORB to do something differently in certain situations, so you may
want
to take a look and the omniORB API to see if you can gain a little more
control over thread/connection management.

At this point, I'm afraid you're at the limit of my knowledge....  Good
luck!

--Ken.
