Would it be difficult to add a few features to ddb configurable via
sysctl?  Like:

1. An unattended console setting (true or false)
2. So if the above is set to 1, then a timeout interval in seconds could
     be set so that a reboot would occur.
3. An option for the reboot to either just reboot, dump core and reboot
     or halt.

FreeBSD has an unattended console kernel option so that a system
would just reboot after a panic.
