xargs short-circuit

After reading the man-page, and browsing around the internet for a minute,
I was just wondering if there is an option in (any) xargs to short-circuit
on first failure of [utility [arguments]].

e.g.

$ jot - 1 10 | xargs -e -n1 sh -c 'echo "$*"; echo exit 1' worker || echo $?
1
1

such that any non-0 exit code in a child process would cause xargs to stop
processing.  seems like this would be a nice feature to have.
