Yeah, but a repeatable segfault certainly is an adequate tool for a
denial-of-service attack, since it takes out everyone else's sessions
along with your own. A possibly larger objection is how sure can you be
that the effects will *only* be a segfault, and not say the ability to
execute some user-injected machine code.
