Maybe that would be too encoraging for broken code.
Admittedly I did that by hand for the MPT fusion driver (which currently
triggers the watchdog when it gets into any error handling situation)
This especially hurts on x86-64 which runs the watchdog by default.
But it's strictly a bad hack, not a good interface.
