Can you define 'reasonably short time'?
If they come back faster than a single SCSI timeout: we are covered.
Otherwise, I'd say we should place the limit at 'We can only queue so
much until we run out of memory'; alas, the failure case which you bring
up is swapping to a fully disconnected m-p device under OOM, and that's
pathological.
