+many. We have this wonderfully scalable algorithm to do the view
indexing, and then it's only used with 1 thread at a time! I've never
really understood why that is (even though I understand that the
algorithm being scalable doesn't help with serializing things on disk
and whatever else).

Also, a mode that will update all the indexes (asynchronously) on
insertion/updates would probably be something we'd use. It seems to me
Couch is better at read-heavy loads than at write-heavy loads, yet the
index-on-access seems optimized for the latter!
