Note that these are simply limitations of what has been done out of
developer interest, not fundamental ones of design.  I'm not in the
business of writing system shells, so I (nor anyone else) never implemented
full-fledged job control.

If you do it and send it in, we'll be happy to include it.  And I suspect
IPython does a LOT of stuff already that you'll spend a fair amount of time
rewriting from scratch, so perhaps helping in to fill in the missing pieces
might be a good investment of your time.
