A memory-mapped file can be renamed, so replacing the executable is doable. The new name has to be on the same volume. That's doable. The problem is that Windows doesn't allow deleting the file. Maybe pip could spawn a clean-up script to which it pipes the list of renamed files. The script waits for pip to exit and then tries to remove the files. -- https://mail.python.org/mailman/listinfo/python-list
