Log message:
setitimer(2): ITIMER_REAL: use kclock timeouts
Reimplement the ITIMER_REAL interval timer with a kclock timeout.
Couple things of note:
- We need to use the high-res nanouptime(9) call, not the low-res
getnanouptime(9).
- The code is simpler now that we aren't working with ticks.
Misc. thoughts:
- Still unsure if "kclock" is the right name for these things.
- MP-safely cancelling a periodic timeout is very difficult.
