I think it is a design-mistake for the proxy to react to the forced
reload of a huge object, when is already busy processing that object
and have not delivered it to any clients yet.

Given that the client has not seen the object yet, the client has
no basis for conclusing it is out of date, so the reloads should
be ignored, the requests queued and once the object is processed,
you can deliver it.
