Guido van Rossum added the comment: Shouldn't we just close the issue and the unused PR? Otherwise we'll just have yet another vague bpo issue that doesn't have anything particularly actionable -- "there's some code that could be refactored" is not enough of a reason to have a bpo issue

Guido van Rossum added the comment: Honestly I find it debatable whether we're doing anyone a favor by publishing the __file__ of the corresponding stdlib file for frozen modules. There will be situations where this points to the wrong file, and editing the file will not have an effect

New submission from Eric Snow : Currently we calculate a number of filesystem paths during runtime initialization in Modules/getpath.c (with the key goal of producing what will end up in sys.path). Some of those paths are preserved and some are not. In cases where the discarded data comes
