| This patch changes the _Environ subclass of UserDict to use dict instead, which avoids the import of UserDict, save 6-8ms on python startup with site.py (~4% improvement). I tested this on my MacOS X box, but since this code is really only used in Win32, someone should test it there. | ||

| Logged In: YES user_id=21627 The patch is incorrect. dict has no attribute data, and subclassing from dict involves many more changes than just changing __setitem__/ __getitem__. | ||

| Logged In: YES user_id=430343 Patch is broken, and not really worth fixing for the performance gain. |
