My guess is that he's worried that we'll end up with lots of additional
'indirection' through the system, thus slowing down the ability to
service interrupts in a quick manner.
Also, don't fast interrupts depend on the ISA bus? Fast interrupts are
a requirement for *any* machine to run at a reasonable speed, old/slow
or new/fast, it doesn't make any difference.
