This is true.

The threads to accept incoming connections are started when you first
acquire a reference to the Root POA. No operations are dispatched
until you have activated at least one POA, of course.

omniORB always dispatches calls on its own threads. ORB::run() simply
blocks the calling thread until the ORB is shutdown.
