  SVN rev 200021 on 2009-12-02 10:10:37Z by mav
  
  MFC r199279, r199280, r199281:
  - Fix several device freeze counting bugs.
  - Remove code that years ago was closing race between request submission
  to SIM and device/SIM freeze. That race become impossible after moving from
  spl to mutex locking, while this workaround causes some unexpected effects.
