This statement is absurd. Only a comptetant admin can decide
which process can be killed. No arbitrary decision is going to be
correct.

In case you hadn't noticed, this debate is cross-posted to
NetBSD. NetBSD's target market isn't the same as FreeBSD's target
market. This answer is NOT the correct solution for NetBSD's target

mission critical servers.
