one case where we do, I think (but perhaps this is not
`sharing' in the sense that we need to save and restore tty
state)). I don't know if there is any way to tell whether we
are sharing a terminal. So what we do is to go through all
the saving and restoring of the tty state, but ignore errors
setting the process group, which will happen if we are not
