Trying to contact an object which no longer exists should result in
either an OBJECT_NOT_EXIST exception if the object's process is still
running, or a COMM_FAILURE if the process isn't there any more.

Normally, you'll receive these exceptions very rapidly, but in the
case that the host is not reachable by TCP (or the process is
suspended), the default TCP timeout will block the call for a long
time. You can make the time shorter with -ORBclientCallTimeOutPeriod,
or omniORB::callTimeOutPeriod().

Cheers,

Duncan.
