  Issue 6070: when creating a compiled file, after copying the mode bits, on
  posix zap the execute bit in case it was set on the .py file, since the
  compiled files are not directly executable on posix.  Patch by Marco N.
........
  r73879 | r.david.murray | 2009-07-07 05:54:16 -0400 (Tue, 07 Jul 2009) | 3 lines

  Update issue 6070 patch to match the patch that was actually tested
  on Windows.

  r73899 | r.david.murray | 2009-07-08 21:43:41 -0400 (Wed, 08 Jul 2009) | 3 lines

  Conditionalize test cleanup code to eliminate traceback, which will
  hopefully reveal the real problem.

  Make test work with -O.
........
  r73905 | r.david.murray | 2009-07-09 09:55:44 -0400 (Thu, 09 Jul 2009) | 3 lines

  Specify umask in execute bit test to get consistent results
  and make sure we test resetting all three execute bits.

  Curdir needs to be in the path for the test to work on all buildbots.
  (I copied this from another import test, but currently this will fail if
  TESTFN ends up in /tmp...see issue 2609).
