Well my reasoning for having "0" mean don't timeout,
was to have an easy way in scripts to specify no timeout, like:

timeout=0 # none
[ "$platform" = "buggy" ] && timeout=10
timeout $timeout command

I'm unsure whether to make this change.
If we do I guess `timeout` should immediately exit(124).
This change in behavior would need a mention in NEWS anyway.

cheers,
Pádraig.
