Fix rpmlint: non-executable-script...

Fix rpmlint: non-executable-script """ This text file contains a shebang or is located in a path dedicated for executables, but lacks the executable bits and cannot thus be executed. If the file is meant to be an executable script, add the executable bits, otherwise remove the shebang or move the file elsewhere. """ Mostly deleting the shebang, but some files contain a __main__ function, so make them executable. This is the last commit of this series and: Closes gh-647.

      """Minimal script to reproduce our nasty reference counting bug.

      The problem is related to https://github.com/ipython/ipython/issues/141

      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.

      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 2011-05-29,

      test_run.py calls it.
