Why is that? I don't see how the list of changes is ordered. ISTM that
updated documents may be passed to the view indexer in any order,
which is why M/R works. If that's true and computing keys and values
is CPU-bound, parallelizing running the view function on the updated
documents shouldn't be that hard.

Cheers,
