This explains why you sometimes get less than 30ms sleep times. If an event
reaches the process before Timeout, then the timeout is not triggered.
Also, it may explain the jitter you are seeing, because an early event will
reset the timeout. Try using gen_fsm:start_timer/2 or erlang:send_after...

If the problem persists, check lcnt. If you are locked on the timer wheel,
then consider release 18 :)
