[omniORB] Bug in omniORB 3.0

Hi,

Okay, got round to this at last!  Sorry about the delay.

Yes, this is a bug in <omniORB>/src/lib/omniORB2/orbcore/policy.cc.  I'll
put the fix in CVS tonight.  It is a ref counting problem for policy
objects.

However, there is also a bug in your code ... see below.

This requires the USER_ID policy, which the root poa does not have.
Perhaps you meant to activate the object in the _worldPoa?
