I'd also like to see your camcontrol detach patches and a path for vinum
to lose and then reattach a volume.  Whether the latter should happen at
the CAM layer or the vinum layer is up for discussion.  I personally
believe you should be able to tell vinum to close its reference to the
drive that went away and then re-open it when the drive reappears.  This
could even be done automatically through GEOM.  (See Gordon Tetlow's work
on adding volume labels to GEOM).
