Windows does not allow renaming files that are currently open, or directories that contain open files. When antivirus software is used, files are open for analysis by the A/V software, making it impossible to rename files too quickly after they've been created.

This was already reported in #992 and addressed, however the issue was re-introduced in #3724, in which tarballs were extracted into temporary directories that were then renamed.

Changed the code back to a form taht extracts files directly into their final place instead of staging via a temporary space, and added comments warning maintainers about the specific issue being solved here, so that hopefully the problem does not get re-introduced again in the future.

Fixes #3751
