This message is currently displayed on, which is sitting
at a kernel debug prompt, but works as a slip <-> ethernet router and can
be pinged.  Interesting  --  I'll leave it like that for a while  ;)

vm_fault(f8214000, ff000000, 1, 0) -> 1
kernel: page fault trap, code=0
Stopped at      _vrele+0x5b:    movl    0x60(%eax),%eax

This is very common to both junkbox and packrat.  I have removed all the
sources and recompiled *everything* in the last few days, but still have this
problem, as well as the random seg faults when running compiles and other
semi-big processes.

Here's my config file, maybe someone will point at something and say ``oh,
you dork -- take out FOO cause it's broken''  :)
