``Not I,'' said the pig. (Since I just ate half a dozen chocolate
chip cookies, I think I qualify. :-) )
Seriously: I never produced this particular bletcherous hack. (I am
responsible for a number of other, different bletcherous hacks, but
not this one.) If (A) you have SIGSTOP and (B) signals work correctly,
the super-user can stop everything, pick out the bad processes, kill
them, and then resume everything. (This is a bit tricky to get right,
admittedly.)
