Attachment: main.js.patch
> [PATCH] speed up toJSON()

> This patch is a trivial optimisation of the toJSON() function in main.js
> It provides a surprising speedup. For example, in my real-world app, it
> reduces indexing time of ~3,800 docs from 80 seconds to 60 seconds. And using
> the benchmark script I posted to dev@, I see:
> 2.877 -> 2.062 secs (3000 docs, emit one k/v per doc)
> 13.522 -> 7.585 secs (3000 docs, emit 10 simple k/v per doc)
> 19.049 -> 12.714 secs (3000 docs, emit 10 compound k/v per doc)
