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. END
