Ok. Well, if the changes to storeio succeed in making that libstore calls
we think are right (and in particular deactivating the store when peropens

Gnumach doesn't close device when last send right is released. If you do
dd if=/dev/hd2 of=/dev/null bs=1k count=1
kill /* pid of /hurd/storeio hd2 */
cdrom (hd2) door remains locked.

In oskit-mach, device_close is a no-op and releasing the last send right to
the port returned by device_open is what closes the device. Then there is
nothing extra to worry about, even in case of untimely death of translator.
So there.

etc. lock CD (hd2): devprobe and storeio call device_open, which
calls cdrom_lock_door, but they don't call device_close, which unlocks
CD! (Should Mach call device_close, when there are no send rights to
the device port?)
