This might be useful, but it looks like I'm able to get everything to 
work even without it. I've always used "orbit-local-mt-orb" rather than 
"orbit-local-orb", though. I think that means CORBA_ORB_init() sets up 
everything so that the ORB may be used across threads, but doesn't 
actually add any threads of its own.
