Fix bug: https://bugs.launchpad.net/ipython/+bug/269966 This fixes a long-standing and serious problem with long-running IPython sessions. Finally! Many thanks to John D. Hunter and Sameer D'Costa for the feedback, especially for Sameer's patch that finally put me on the right track for a clean solution.
