This is by design. ugen is really a full driver with a userland interface.
Yanking the device from under its feet and assigning it to another driver
is a difficult thing to get right.
A solution that has been proposed is to provide each driver with a 'generic
interface', similar to the pass nodes in /dev for each SCSI device. But this
creates other problems.
