I think we should wait and and see if people complain about the loss
of job control; I'd rather see us fix the problem with TIOCSTI.

I don't think we need to fix this for runcon, as it isn't as
sandboxing tool like sandbox, and the loss of job control would likely
be much more noticeable for runcon.
