vm PANIC on RC1

Hello,

I grabed this trace after my machine panics. This happens if I run links to 
swat on the local box over ssh forwarded X11
II have ZERO_COPY_SOCKETS in my kernel and I'll try Andrew's patch, but I 
wanted to make sure this panic is seen by somebody who can read it ;)

Thanks,

-Harry
