Author: afa
Date: Sun Sep 12 22:07:25 2010
New Revision: 77028

Added:
   pypy/branch/fast-forward/lib-python/modified-2.7.0/test/   (props changed)
   pypy/branch/fast-forward/lib-python/modified-2.7.0/test/test_sys.py   (contents, props changed)
Log:
Add a customized version of test_sys.py

So far, only skip 2 tests as "implementation details"
(about reference counting, and sys._current_frames)
