Using the Fcopy_sequence function, I'd think. Use it at the beginning
of the function to set the value of 'idle_timers', instead of this
line:
idle_timers = Vtimer_idle_list;

timer_check_2 indeed returns, but then timer_check will call it again,
because it continues calling timer_check_2 in a loop, until there's no
ripe timer.

It isn't useless, it just means a slight delay in the "now" part of
its doc string.
