[omniORB] Two orbs only one registered.

[Bruce Visscher]

While you cannot have more than one orb per process you can certainly have
more than one POA.  I think this might be what you are looking for.

On the other hand, keep in mind the threads that handle dispatching requests
via POAs are not necessarily the only ones to consider.  You will likely
create other threads and you can control the scheduling policy and priority
of those threads.

You should read Henning and Vinoski's Advanced CORBA Programming with C++
for more details.
