  SVN rev 210646 on 2010-07-30 13:23:21Z by jh
  
  MFC r207671:
  
  Fix deadlock between GEOM class unloading and withering. Withering can't
  proceed while g_unload_class() blocks the event thread. Fix this by not
  running g_unload_class() as a GEOM event and dropping the topology lock
  when withering needs to proceed.
