I'd noted, that this have changed in 1.3: view server may receive
multiple map_doc commands before he return some result. This mean,
that view server may be process documents in async way for some cases,
when document mapping is a long and heavy process. However, view
server should return response in the same order as documents he
received, but this may be changed if view server will return result
with document id on board, so CouchDB will know for which document
this kvs are belongs to.
