ReiserFS is said to slow down considerably if it gets past 85% full.

That depends on when you look I guess, and in this absolute form the
statement is probably wrong, however, with the growing number of mappers
and tiles at home renderers this will become more and more true.

While it were possible to limit re-renderig of tiles (ie. don't render a
tile if it has been rendered in the past X hours) but I'd rather not go
down that path.
If it helps I can donate a second 160 GB IDE drive to help spread the
load out over several disks (ie. put the maplint layer on there).
