In any case, if a process is sleeping in-kernel, I expect that either
it's an
interruptible sleep or a guaranteed-short sleep. If it's neither, it's
a bug. If
I kick out an ethernet and it makes "ping" hang in "D", that's bad. I
think
that eventually _all_ kernel sleeps on the behalf of user-space
processes
will become interruptible.
