	You're correct.  However, you took my words out of context.  The idea
is that if you have multiple track buffering, you still want to group the
first data blocks together, just not put them on the same cylinder as the
directory.  C-A's idea of putting the first data block on the directory
track is a feature only if you do not have multiple track buffering, which
we currently don't.

	If you think about it, *everything* will go much faster with multiple
track buffering and read-ahead.
