I believe I stumbled across that earlier, unfortunately that key doesn't
exist on my system. I am able to strace/gdb right now when my squid
isn't stuck, so I've attached via gdb and then left it running in
screen. Hopefully next time it breaks I'll be able to get back in and
grab a useful stack.

Thanks for the suggestion.
