Last I mucked about with this code, it would handle passes sequentially
but disks[1] in each pass in parallel.

The reason for doing it this way was that there is no way to see from
/dev/ccd0 which drives this would affect, this using passes to control
when ccd devices where handled allowed manual sceduling.

If people have changed it since then, I'm not aware of it.


[1] A disk being defined as anything in the device name up to and including
the first numeric sequenc of characters.  Ie: "ad0s4b" is on disk "ad0"

Never attribute to malice what can adequately be explained by incompetence.
