" I also seem to remember there being something really bad about context
" switching with the i860.

didn't someone earlier say it had a really deep prefetch pipeline?
that's an architectural mistake for a multitasking environment, since
it has to be dumped on every context switch.  branches too, unless it
can prefetch both legs of the branch, but that's more foreseeable than
context switches.
