 Description   

When a reader wants to know the latest count/dataSize value, we should first apply any unapplied Deltas before returning the latest value to the caller.

Not sure whether it's reasonable to fetch the all_durable timestamp from WT every user read. It might be. Also could consider whether to use other in-memory system timestamps – maybe even the oplogReadTimestamp.
