It sometimes helps to call revoke(2) on a pathname that refers to the
device that is wedged.

Perhaps we need a new syscall to *really* kill a process, even if it's
in a state where normal signal delivery does not happen.  Late 1980's
Apollo Domain-OS had a "kill -lbolt" command that sent a "lightning
bolt" that worked even where "kill -9" did not work.
