Thanks for the long reply and fixes. That argumentation of
yours makes a lot of sense.

I'll see if I can help.

I'd still find that useful. Though I suppose that's where I can
use gxargs -P instead.

I've just posted


that would help covering the --no-shell aspect over ssh (ssh
always invoking a shell is one of the things I find most
annoying about it, that and no easy way to kill the remote
command upon connection loss which you also ran into).

Even outside --no-shell, you may still find it useful to
abstract yourself from the user's login shell on the remote
