[omniORB] is the orb a singleton

[ERIKSSON,TOBIAS (A-Sweden,ex1)]

Hi 
 Is the orb-object (CORBA::ORB_var orb = CORBA::ORB_init( argc, argv,
"omniORB3" ) ) a singleton object?
 What I am after is this, if I would in my application/server use the orb
everywhere in the application, cause otherwise I would have to have some
class that had the responsability over the orb-object so that it is only
created once and accessed many times.
