As George Robbins points out, dump accepts the `-b' flag.  The maximum
value for this flag is 126, as in 126 blocks or 63K.  This works for
tar, too, and speeds up the TK50 a lot.  I don't know whether values
between 20 (the documented maximum for tar) and 126 work.  Don't forget
to specify `-b 126' when you restore an archive.
