nico@210: if simply outdated
nico@210: ask for trig
nico@210: or period have expired
nico@210: set val as interval, with overrun correction
nico@210: Check if this new timer value is the soonest
nico@210: Each armed timer value in decremented.
nico@210: Check if this new timer value is the soonest
nico@210: Remember how much time we should sleep.
nico@210: Set timer to soonest occurence
nico@210: Then trig them or not.
nico@210: reset trig state (will be free if not periodic)
