The timer resolution is less than 3.5 microseconds. I measured with a
little C loop. 1ms is definately not accurate enough as an incremental
GC takes 0.3 milliseconds on my machine.

I'd love to see a better GC too. But on my system I've yet to see the
incremental GC take most of the time however that should change as
Exupery becomes useful.
