  We recently discovered that on some systems adding a share using
  sharemgr took 15 seconds.  This delay was tracked down to
  smb_enable_service(), which includes the following code:

                /* Wait for service to come online */
                for (i = 0; i < WAIT_FOR_SERVICE; i++) {
                        if (smb_isonline()) {
                                ret =  SA_OK;
                                break;
                        } else {
                                ret = SA_BUSY;
                                (void) sleep(1);
                        }
                }

  Diagnosing the problem further showed that smb/server wasn't 
  available.  In particular, it was in the maintenance state, which
  means that until an administrator does something, it will *never* be
  available.  smb_isonline (which is already checking the state of the
  service) should test for that so we can fail quickly.
  
  This problem is exacerbated by the fact that no error is returned to
  the user.  I don't know if that is correct or not (I'd guess no), but
  one outcome is that it takes considerable effort to determine why
  sharemgr is behaving erratically.
