orb.run() does not do anything - it just blocks the calling thread
until someone else call orb.shutdown(). It is not necessary to
call this at all if you don't want to block your main thread.

In the example, the main() method in Client.java only starts
ClientThreads. Client itself exits after creating these Threads,
and the threads themselves are busy firing off invocations, so
they don't need to block either. Calling orb.run() is only 
necessary if the Threads' run() method would otherwise exit.
