How are the 10 simultaneous write requests handled ? Won't there be

I would guess that it processes all 10 operations in memory sequentially, then writes the
combined results to disk. If one of them conflicts with an earlier one, it’s rejected and
evaluation continues to the next.

(But I have no first-hand knowledge of the innards of CouchDB, I only know the architecture,
so this is just speculation.)
