But AFAIK this is a problem that was already there in minix 0.6x (some long
time ago (about two years) I posted a message concerning this.
Everytime you have a _very_ big directory minixfs is awfully slow.
There was another bug included that caused damage when having a file
bigger than 64mb. Torsten fixed this bug long ago.
