- This is *not* used when permissions prevent removing the file itself:
- that will be raised as a regular PermissionError (OSError on Python 2).
-
- Application code that catches this may try to simply delete the file,
- or prompt the user to decide, or (on Freedesktop platforms), move it to
- 'home trash' as a fallback. This last option probably involves copying the
- data between partitions, devices, or network drives, so we don't do it as
- a fallback.
