Whatever is going on is subtle....My unicodedata.pyd does not change.
Hey wait, you said

"...bz2.py, unicodedata.py and zlib.py files..."

My Python 2.4 doesn't have a file named unicodedata.py, zlib.py, or
bz2.py what's up with that?  On my system these are all .pyd files and
they are not generated as they are binary extensions.
