Sounds great to me :) Another device that needs its interrupts to be
handled promptly is the serial port; I seem to recall that we can keep
up with 57600 baud as long as there's no disk access (it's been a while
since I've used the serial port though, so I may be recalling
incorrectly :). Maybe with your changes, we'll be able to do the same
even with disk I/O going on?
