So 137 is only used when the signal was sent to timeout itself?

I'd have actually found it quite nice if 137 was used *even* with
--foreground.

That way one could differentiate between whether COMMAND had the chance
to do cleanups, or whether the calling process should take care on
that.


For example, I use timeout with a program that reads a phassphrase and
prints it to stdout.
It disables the terminal's ECHO, so when it has to be killed, the
calling process would need to re-enable that mnually.


Cheers,
