Follow-up Comment #1:

That was an interesting problem.  The issue is that child_error is changed in
wait_for_all() after exit() has already been called on (since we fall off the
end of main()).   That means that it's too late by then to change the return
value.  As a workaround for this problem we now call _exit() when this
happens, passing the correct return value.    It might have been neater to
just call wait_for_all() before returning from main().  Anyway, the attached
patch (which I have committed to the development code) fixes the problem.
