  SVN rev 195509 on 2009-07-09 18:54:38Z by kib
  
  The control terminal revocation at the session leader exit does not
  correctly checks for reclaimed vnode, possibly calling VOP_REVOKE for
  such vnode. If the terminal is already revoked, or devfs mount was
  forcibly unmounted, the revocation of doomed ctty vnode causes panic.
