If we ever want to make that PageLaunder thing reality (well, if we realy
want a decent VM we _need_ that) we need to make the accouting on a
buffer_head basis and decrease the amount of data being written out to
disk at end_buffer_io_sync().
The reason is write() --- its impossible to account for pages written
via write().
