Decided to update my source tree today. Evidently this was not a bright
move. I built my kernel and whatnot, powered off (rebooting on my
laptop doesn't work...), and startx'ed. Then I ran mozilla.
poof

---Can't read userspace from dump, or kernel process---
And there you have it. I cannot begin to fathom what caused this. So far
it seems that only running mozilla causes it to occur.
I can supply more information if needed of course.
