It used to be worth while to allocate the VTOC so that the last track
ended at the end of a cylinder regardless of where it started.
This allowed multi-track search CCWs to be used.
I don't know if this is still true, or if VTOC searches have been
updated to use ECKD CCWs. Of course with VTOC indexes, searches are
a lot less common at least for code that has been updated to use the
index (hopefully most by this time).
