[Borgbackup] borg delete failed

That call should completely remove the directory and all stuff inside.

>> OSError: [Errno 39] Directory not empty: '20'

But it failed to do so, because there was something inside a directory 
when it tried to rmdir that directory. It usually does the rmdir 
**after** removing all stuff inside the directory (files and subdirs), 
so that is unexpected.

Possible explanations:
- there was acticity in that directory in parallel (should not be borg, 
because borg delete locks the repository). did you use borg break-lock?
- filesystem malfunctioning
- bug in shutil.rmtree

Yeah, but that should do a quite similar thing as shutil.rmtree does.
Maybe it was successful because then there was no parallel activity or 
the fs behaved better that time.
