That actually does work quite well.

Even with ONE controller, it's not bad.  ISC >will< overlap seeks to the two
devices, IF your controller can handle it.  If not, you have to turn off
that feature in the space.c file for the device (it's on by default); this
is the cause of some problmes with certain revisions of the WD1006 boards.
