Work again on bug 269966....
r1916 """Minimal script to reproduce our nasty reference counting bug.
The problem is related to https://bugs.launchpad.net/ipython/+bug/269966
Fernando Perez
Small formatting fixes to address Jorgen's last code review.
r1922 The original fix for that appeared to work, but John D. Hunter found a
matplotlib example which, when run twice in a row, would break. The problem
were references held by open figures to internals of Tkinter.

Fernando Perez
Small formatting fixes to address Jorgen's last code review.
r1922 This code reproduces the problem that John saw, without matplotlib.
This script is meant to be called by other parts of the test suite that call it
via %run as if it were executed interactively by the user. As of 2009-04-13,
test_magic.py calls it.
