Seems to me that ought to be calling zwarn().

That's good.

No, that's got to be wrong.  Since killrunjobs() is never called from
anywhere except zexit(), I think using zwarn() rather than setting and
then clearing errflag is the way to go.

So, my suggestion is to use only the math.c hunk of Sven's patch, and
use this instead of the builtin.c hunk:
