  38 # NB: For a naive exact match, there is a race condition here, as
  39 # 518.out expects exactly three evaluation rounds to be complete by the
  40 # time the following operation is invoked.  If sudo/pmie is too slow,
  41 # it'll lose the race (actions<5).  If this thread is too slow, pmie
  42 # will go ahead (actions>5).  So we tolerate values in the range 4,5,6-9
  43 # for the true, false and action counts, but the counts for each must
  44 # be equal.
