----------------------------------------

Hi Bob, can you be a little more specific on this proposal?  What does it mean to "handle bignums" -- does anything change in the mochijson2 decoder?

Do you want to make the encoder always encode integers larger than N as strings?  I kinda dislike that default because it becomes impossible to roundtrip a bignum through mochijson2.

> CouchDB uses spidermonkey which can only handle 32 bit integer values before overflowing. This might surprise users of map/reduce on large datasets.
> Instead, alter mochijson2.erl to handle bignums and encode numeric values as strings.
