no idea why, but this is not allways the case too :-/ I give up for this 
night... maybe tomorrow i've got better ideas.

i'll look into the mechanism i use to store directory data in bufs 
associated on the directory's vnodes... maybe the buffer cache doesn't like 
this though LFS also seems to use it.

Also i'll try running without yamt's patch though i doubt it'll make a 
difference since i've seen this happening before.

sleep well,
Reinoud
