    The timer interrupt is re-enabled, via the timer_sysclass::resume hook,
    while the timekeeping code is re-enabled via the
    timekeeping_sysclass::resume hook. The issue being that I'm not sure
    there's a defined way to specify the .resume calling order.

    The timekeeping_suspended flag is a bit heavy handed, but I think it
    might be the safest bet (assuming Mikael finds it works for him).
