The problem is general to cases where a current-shell construct on the left
of the pipeline contains an external command.  It doesn't matter what's on
the right of the pipeline.  The code on the left seems to be executing all
right.

% exec 3>&2
% { ls; print Finished >&3 } |& cat
Finished

and it hangs in zwaitjobs, waiting for the job to finish, which it never
does.  Change `ls' to `print foo' and the problem goes away.
