I think one motivation was to have boards reboot automatically avoiding
the need to walk over to the board just powercycle or reset it - let
alone reseting by emailing/phoning an admin!

But that's a development-specific motivation and it shouldn't result
in a hardcoded reboot timeout for everybody.
