Um, actually, all that paragraph states (in a very indirect way) is that the
thread executing main() needs to be held alive in order to keep the
application containing the Hello servant alive, so that the POA can fire
requests to the servant object as they come in. It really doesn't answer the
question in the slightest.
I'm not a CORBA expert, but I believe the OMG specs state that a CORBA call
can come in on any thread, so you must assume complete nondeterministic
behavior--synchronize anywhere shared resources are being referenced. This
is the same policy as is required by RMI, so any RMI book that talks about
synchronization (which is precious few of them) would be of a help here.
