There are no filters in omniORB -- such things are outside the CORBA
spec., and are therefore non-portable. omniORB has a threading model
in which each IIOP connection is managed by a single thread. New IIOP
connections are created on demand, so multiple invocations between a
client and a server can be in progress at once.

So, if you just want to be able to call operations of an object
concurrently, either from a single client or multiple clients, then
omniORB automatically supports it. If, on the other hand, you want to
have an operation which starts a new thread, and then returns to the
caller before that thread has finished, you'll have to do it within
the operation implementation.
