In : _ip.magic("history")
The strange thing is that with the patched Magic.py none of the ipipe
tables work any more. If I remove all my changes from Magic.py except
the import (from IPython.Extensions import ipipe) it's still broken.
Moving the import into magic_history() fixes the problem.

You're right, I think this kill it. Another option would be to never
output anything via an ipipe display unless it's explicitely requested.
With a prefilter hook this could be shortened to one character:
ils | isort^
would get mapped to
ils | isort | ipipe.defaultdisplay()
