Also, I should have mentioned originally that by default on recent
trunk, the mochijson2 encoder has been replaced by default with a
version that uses C extensions instead of native Erlang. Only when
these are not available will the pure Erlang version be used.
Depending on the version of CouchDB and Erlang that you use, this will
be important in comparing differences.
