No. What the SINGLE_THREAD_MODEL guarantees is that only one thread
will call into that POA's objects at a time. It makes no guarantee
that it's always the same thread, and has nothing at all to do with
how threads are used by different POAs. There is no notion in the
CORBA standard, or in omniORB, of having separate threads for
different POAs.

Read the POA chapter of the CORBA core spec.

Cheers,

Duncan.
