This is probably related to another continuing thread --- it's likely to
be because the anonymous function was originally running in the current
shell, and the entire shell was forked to continue running it in the
background.  This doesn't have the same job text a normal process would
have --- both a straight "cat" and "( cat )" are running as separate
processes from the start.

It's probably possible to do better but quite how hard it's going to be
dragging the job text round the houses I'm not sure.
