  Dirsync is somewhat similar, except it's 
used to guarantee the write completes
serially and synchronously. It's therefor
a performance pessimization, somewhat like
the sync mount option (;-))

  I was just talking about the need to 
request directory updates as they come in
and in order, as opposed to delaying
and reordering them.

  Ian's thesis actualy went into the
degree to which one could delay and reorder 
directory writes, but I didn't want to add
that complexity to a very short email.
