Hash :d71a0d64 Message :getitimer(2), setitimer(2): ITIMER_REAL: call getnanouptime(9) once
Now that the critical sections are merged we should call
getnanouptime(9) once. This makes an ITIMER_REAL timer swap atomic
with respect to the clock: the time remaining on the old timer is
computed with the same timestamp used to schedule the new timer.
