Raising a minor point here for discussion, rather than on JIRA.
With feed=continuous, the newline after the last record isn't sent until the
*next* record is available. For example:
$ telnet localhost 5984
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

--------------------->
stops at end of line
When the next record is generated, it adds <comma> <newline> <record>.
Whilst this makes the feed pretty to read, it doesn't make it easy to parse,
as you basically need a full JSON stream parser to delimit the record. Or
else, you're always one record behind.
Wouldn't it be better to send the record followed by a newline, and then
<comma> <record> <newline> for the next one? That is,
{"results":[
{"seq":1,"id":"1f9bcccaadf2c3e9508d42532838595f","changes":[{"rev":"1-23202479633c2b380f79507a776743d5"}]}
