Bill and I dug through disksort() (including lots of instrumentation),
the IDE drivers, and a bunch of the buffer cache code on Friday.  Though
I don't think my x86 assembly is really up to it, I was planning to look
at the low-level interrupt handling code next.  I'm starting to wonder
if maybe we're not always restoring the correct mask or something like
that -- why would we lose with *some* interrupts but not others?
