Subject: [PATCH] Add a patch to 'halt' that will shutdown all the processes
within contexts before everything else.
This is necessary because without this, a node would try to shutdown but hang
indefinitely with error messages like:
umount: /vservers/<slicename>/proc : device is busy
umount2: Device or resource busy
and finally:
INIT : no more processes left in this runlevel
But not actually reboot. This patch has worked in an alpha env where the
original halt script had failed.
