This is really bad idea, please back it out. You are certainly
going to get a pagefault in virtually EVERY consumer of malloc. It
turns easy to debug calls into a "page fault" ie. "buggy" looking
kernel.
Bad press, bad idea, back it out, no cookie. :(
You go from:
"I installed freebsd, exhausted some limits and the machine blew."
to:
"FreeBSD falls over with 'random' panics when faced with large load."
