An update for you from my last one...

I compiled mutt out of pkgsrc as a replacement to see what it'd do and
used all defaults (basically, "cd /usr/pkgsrc/mail/mutt && make && make
install"). The resultant binary appears to be stable; I can't seem to
crash the system with it.

I next decided to put the system under heavy load to get it to panic
again, which it had done in the past.. and it did. At the time of the
panic, I had a kernel compile running as well as 4 items out of pkgsrc.
The result:

vm_fault(0xe1b3518, 0x0, 0x1) -> 0xe
trap type=0x8, code=0x145, v=0x4
