Is there any good reason why 0.02 seconds is the best that you can get
here? Couldn't GHC's internal timer tick at a _much_ faster rate (like
50-100µs or so)?

Simon, the talk is about changing GHC _tick_, which is a _minimal_
possible context switch interval. so, we want to decrease this tick
and retain current 20 ms _default_ switch interval. this will make
possible to decrease switch interval for programs that really need it,
which is currently entirely impossible.
Yes, I know.
Cheers,
Simon
