[New-bugs-announce] [issue40103] ZipFile.extractall is not multiprocess safe with regard to directory creation.

[Nathan Silberman]

New submission from Nathan Silberman <nathan.silberman at gmail.com>:

When extracting multiple zip files, each from a separate process, if the files being extracted are in nested directories and files across zips contain the same parent directories, the extraction process fails as one zip attempts to create a directory that was already created by the extraction call in another process.
