  SVN rev 213932 on 2010-10-16 19:53:22Z by bz
  
  MfP4 CH182763 (original version):
  
  Make it harder to exploit certain in_control() related races between the
  intiial lookup at the beginning and the time we will remove the entry
  from the lists by re-checking that entry is still in the list before
  trying to remove it.
  
  (*) It is believed that with the current code and locking strategy we
      cannot completely fix all race.
