ted,

stop right now. running a process (even with root privileges) is not
giving life and death authority over the system.

it is a bug that a userland program can cause the kernel to crash with
a vm panic. panics are the safety belts of the kernel and triggering one
of them means that you've found a case that the programmer(s) know
shouldn't happen.

a panic means the situation has been considered before and it is something
that is known to cause problems. finding real life cases of the panic
with reproducable scenarios is _HELPFUL_ to the programmer(s) in finding
bugs in the subsystem.

please stop spreading FUD to users who are trying to report an actual
bug and are providing meaningful data. your emails on this PR are not
only unhelpful, they're detrimental to getting the real problem fixed.

thanks,
