  SVN rev 212778 on 2010-09-17 04:48:50Z by mav
  
  Add one-shot mode support to attimer (i8254) event timer.
  
  Unluckily, using one-shot mode is impossible, when same hardware used for
  time counting. Introduce new tunable hint.attimer.0.timecounter, setting
  which to 0 disables i8254 time counter and allows one-shot mode. Note,
  that on some systems there may be no other reliable enough time counters,
  so this tunable should be used with understanding.
