A number of (generally older) systems have had the concept of numbered
file versions. (I recall seeing this during casual use of ITS, TOPS-20,
and VMS;
GNU Emacs and its derivatives emulate this via the use of .~NN~ backup
copies, but this "pollutes" the directory namespace).
Adding a version/generation number to the filename in the "deleted"
directory would allow multiple versions to coexist.
It might also make sense to populate the "deleted" directory with an
older version when file contents are deleted via an
open(..., ...|O_TRUNC)
or when a file is deleted via rename.
