I think it is safest - and if the underlying storage fails something bad
has happened and anything else we do would make it worse

Just leave the busy bit set forever, the host will get fed up of waiting,
reset, rinse repeat a few times and (except for older Linux) then offline
the device. Older Linux (ie drivers/ide) has problems coping with failed
drives so will carry on spewing but limp along ok.
