The answer is to have a SCSI middle layer that defers (re)queueing
commands to the HBA's until after a (tunable) delay has occurred.
Strictly speaking the delay is a per-target value since the amount of
recovery time after a reset until a target can actually accept selection
is not covered by the SCSI specification.
