[issue40103] ZipFile.extractall is not multiprocess safe with regard to directory creation.

[Nathan Silberman]

New submission from Nathan Silberman :

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.
