Hey Nick,
So I've posted the patch with your Ack, in this thread
http://lkml.org/lkml/2010/7/27/246. I hope that is OK?
I think that using the delayed flushing is appropiate long-term.
I don't know that much about it but I will put it on the list of todo.
Fortunatly that list is actually shrinking (amazing!).
