Message 135037 - Python tracker

I commited mmap fix for Mac OS X, crc test on 2 GB file, and issue #8651 fix into Python 2.7.

Use PY_SSIZE_T_CLEAN in zlibmodule.c is a new feature. I don't want to implement it, I don't need it, and I don't feel confortable in zlibmodule.c. Open a new issue if you want it.

I think that we are done with issue. If you see buildbots failures, reopen it.

Thanks again Steffen for your diagnosis and fixes.
