Err.. not on my machine it doesn't. Which version of orbitcpp / ORBit
are you running.

I'm not sure about this one. If orbit is unable to connect to the
server you get a CORBA::COMM_FAILURE system exception. However if
ORBit has previously connected to the server then you do seem to get a
hang. I'll do some experimenting over the weekend...
