/* Swapping file names is only possible with an intermediate rename,
* and it also means that we can't headlessly replace files.
* For this reason we buffer failing renames until
* the rest of the file operations are completed.
* However, we have the following concerns:
* 1) we don't want to move the file out of its directory,
* so that in case of an error,
* its not lost *somewhere* on the filesystem
* 2) a simple and predictable name is preferable,
* because if an error is encountered,
* we want the user to easily recognize his files
* 3) the temp name might already be taken
* Points 1 and 2 cause 3 to exists.
* To deal with 3, we use the tactic employed by the original vidir:
* + we try incrementing suffixes until something works or we get bored
