    To be fair to Reiserfs, many UNIX filesystems have done this on purpose,
    all the way back to FFS I think. Once free space drops below 10%, they
    change their allocation scheme to favor efficiency over speed. Probably
    this behavior doesn't make sense on a 120GB disk with 11GB free. But it
    certainly does on a 300MB disk when you get down to 30 ;-)
