- Please, monotonic garbage! Imagine extracting such a tape on a system
- which *does* support (non-symbolic) links. I can easily envisage an
- implementation which simply did not initialise the garbage, and wrote
- said garbage the same for each file. On extraction you'd end up with a
- single file with LOTS of links!-)
