[OMPI devel] mpirun hostname hangs on trunk r26380?

[Eugene Loh]

I'm hanging on the trunk, even with something as simple as "mpirun 
hostname".  r26377 and earlier are fine, but r26381 is not.  Quickly 
looking at the putback log, r26380 seems to be the likely candidate.  
I'll look at this some more, but the hang is here (orterun.c):

  935       /* loop the event lib until an exit event is detected */
  936       while (orte_event_base_active) {
  937           opal_event_loop(orte_event_base, OPAL_EVLOOP_ONCE);
  938       }
  939
  940    DONE:
in case anyone recognizes the problem.  This is with Intel, Sun, or GCC 
compilers.
