The POAManager lets you do simple flow control on the POAs it
manages. You might want to be able to configure some of your POAs to
hold or discard requests, while other POAs continue to service
requests. You can only do that if you use different POAManagers for
different POAs.

It's possible that some ORBs might provide threading policies which
group POAs sharing a POAManager in some way. omniORB does not do
anything like that, and POAManagers do not affect threading in any
way.
