I think we might want to change the kernel's behaviour to include the following things: - don't flush if: - there are less than X dirty buffers && - we haven't recently read from the disk - flush if: - there are more than X dirty buffers || - we issued a read from the disk more than Y and less than Z seconds ago || - the dirty buffer is FAR too old (say, an hour or so)
