Don't dismiss job control so quickly ;-).
ipython might even be useful for doing much more "advanced" job control
that what you typically do with bash:
>>> !& tail -f output.log
# launched job, "job object" is in jobs
>>> for line in jobs.output():
if "warning" in line: break
# time passes
>>> jobs.interact() # output comes back to current terminal
I'm not saying I needed this yesterday, but all this might be handy. And
it probably wouldn't be too intrusive on ipython codebase itself, much
of it would probably just be add-on stuff. Throw in some pexpect stuff
and we have something very interesting...

Yup, pysh seemed to work alright. One thing that is still noticeably
slower than on bash is changing the directory with "cd" - on a slow
machine you have enough time to type "ls" and blink an eye before
ipython shows the prompt again. On a faster machine it's ok, obviously.
This is true for both "pysh" and plain unconfigured ipython.
