in case you didn't realise, there's a few cases where we expect to segfault.

for eg, if we mprotect page_rand to PROT_NONE and then something tries to read it.
There's a whole bunch of similar gotchas. I've special cased the sanitise routines
of some syscalls to avoid this sort of thing, but there's a few cases where
a trinity child will corrupt itself. It then dies, and respawns, so I haven't really
worried too much about it.
