> The {code}FileBaseUtils#deleteFileOrDirectory{code} is not thread-safe on Windows.
> First you will run into AccessDeniedExceptions since one thread tried to delete a file
while another thread was already doing that, for which the file has to be opened.
> Once you resolve those exceptions (by catching them double checking whether the file
still exists), you run into DirectoryNotEmptyExceptions since there is some wacky timing/visibility
issue when deleting files concurrently.
