The old novell model is simple. When someone unlinks a file, don't

system.
Such a scheme makes it much more difficult to allocate large,
contiguous runs of free space for storing newly written data.

Possibly. Organize the files in DELETED.SAV by disk location and
date. Files don't have to adhere to a strict date recycling
process. Make it a mount
option if the user wants strict date recycling. Make the default to
choose between date and file sector locality.
