For querying hardware there should be better ways. Have a centralized
place where the information is poll and the broadcast changes. I though
hal etc is supposed to do this.
As for mail pulling: sure. But the frequency should be measured in
minutes and not in micro-seconds.

I assume this refers to the same thing Arjan tried to do: group wakeups
of multiple waiters together. He can probably recall the details more
easily than I can.
