> BackgroundObserver currently merges external events if the last one in queue
> is also an external event. This leads to diff being done for a revision pair
> which is different from the ones pushed actively into cache during backgroud
> read (using JournalEntry) i.e. diff queries for {{diff("/a/b", rA, rC)}}
> while background read had pushed results of {{diff("/a/b", rA, rB)}} and
> {{diff("/a/b", rB, rC)}}.
