Obviously this is being discussed elsewhere. Although I slightly disagree
that you should find out where things can loop for longer than a certain
time. You may not catch them all - in the field, the code path code be
different for some reason.

I don't think it would be too bad to enable interrupts, but be careful to
make off _all_ interrupt sources except for the timer interrupt. You would
then need to unmask any necessary ones before running a downloaded
application.

Anyway, the point I want to make really is that watchdogs normally need to
be enabled before they are used (hardware that relies on system startup
being fast enough is _bad_). I'm not sure it's a good idea to enable the
hardware watchdog at all for RedBoot. Enable it in your application startup
only. If you can anyway.
