Because the omniORB implementation of CORBA::ORB::run() doesn't really
do anything except wait for the orb to shutdown.  In fact, you don't
have to call this if you don't want but in order to be compatable
with other ORBs you might want to do "if (orb->work_pending())
orb->perform_work())" periodically from some thread.

You should read Advanced CORBA Programming with C++, Michi Henning and Steve
Vinoski, section 11.11 "ORB Event Handling" page 506.
