With timers? :)

I'd use erlang:send_after/2 or erlang:start_timer/2 to install timers.
It is quite much faster than the timer module and it should easily be
able to cope with many simultaneous timers. You can also cancel timers
again when you know they are not necessary anymore, but do use the
TimerRef to make sure you don't handle old stray timers. If you are
using gen_fsm's, then they have their own timers which may come in
handy for you.
