when heay write/read of kfs file system, such as those re-compiling
the kernel.

i think there are at least two different sources of bugs here.

before the 27 march update (release) there were some bugs that seemed
to us to be in the paging code, and indeed the march update has made
small but quite significant changes there that appear (to us) to have dealt
with that one.  the only terminal that frequently crashed here has since been stable.
that's good because i was trying to track that down myself
but it seems i was in the right region yet on the wrong track.

unfortunately, that update introduced the portclock bug (essentially, the clock
interrupt ends up disabling itself sooner or later, and because it's now in
the portable code that happens everywhere).  dave presotto fixed it
quickly, but it begins to look as though people thought it was something
they could delay fixing on their own systems.  i don't think it is.
