It's a niggle, but, by "keyboard i/o," I intended to refer to the
entire sequence of steps that is necessary to make it appear to the
user that a keystroke has been dealt with more or less
instantaneously.   As I understand the matter, that would be a fairly
long cascade of interrupts, some of which might, indeed, have to wait
for access to disk.
