Trying to push this forward...  The next step here is a revised
proposal.   I will lobby intransigently for holding out for an
IsolatePorts option distinct from LongLivedPorts: overloading
"long-lived" to "isolated" leads to nonsense like people deciding to
put port 80 into LongLivedPorts, which is exactly what you don't want
to use LongLivedPorts for.
