/* 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
