  Modified files:
    sys/kern             kern_acct.c 
  Provide some anti-footshooting.  Don't allow the user to set the interval
  for acctwatch() runs to be negative or zero as this could result in either
  a possible hang (or panic if INVARIANTS is on).  Previously the accounting
  code handled the <= 0 case by calling acctwatch on every clock tick (eww!)
  due to an implementation detail of callout_reset().  (Tick counts of
  <= 0 are converted to 1).
