>
> If a client application crashes then it can go in infinte loop where same
> records will be delivered. Though previously we chose to decrease the
> delivery count on session release as we didn't have throttling support. Now
> when we do then it makes sense to bump the delivery count on session close.
> Also as share-groups clients should ideally not have pre-fetched data hence
> it's safe to bump the delivery count on session release.
