Reduced the minimum timeout enforced by apic_set_hardware_timer() from

1 ms to 1 us. The long minimum timeout seriously screwed profiling,
since by default it works with 1 ms ticks, stopping the timer when the
thread is unscheduled and restarting it with the remaining time when it
is scheduled again.

I could also imagine that this had a negative effect on latencies and
the precision of thread wakeup times.
