This patch should't be committed - it's messy and not the way Matt
suggested I clean it up, but the commit referenced is absolutely not
the same thing so this shouldn't be marked resolved - unless people
don't want the feature anymore, in which case I'll continue to maintain
the patch for as long as I'm interested in it.

The functionality implemented for this issue (#647), the *host* system
is able to signal the *guest* VKERNEL to shut down cleanly (e.g. when
the host does a halt and forgets to shut down the guest VK's),

With the committed code above, the VK is able to shut -itself-
down cleanly, but the host continues to have no way of doing so -
Signals from outside will kill the VK and leave the VKD's in an
inconsistant state, possibly resulting in a loss of data within the VK

I responded to Matt's commit because I had a second patch in mind that
did the same thing (vkernel *self*-initiated shutdown/reboot) - was
probably going to tackle that later... as I see it, the two
compliment each other..

In any case,
hoping to clean up / resubmit this weekend, more than likely with a
second signal handler to take advantage of Matt's new reboot code.
