The shutdown watchdog timer is something I've had to adjust many times for
many different ports. Given this;

I propose we have (at least) a new rcorder script variable.  Something like
"SHUTTIME" encoding the expected number of seconds required for the daemon
to shutdown in the worst case.

Ideally, you'd want an overall watchdog and a per-script watchdog (so that
you're not waiting the sum of all these times in most cases).
