result2 in callback function?

[dest31337]

Trying to use node-cassandra-cql in async flow control methods which add for next function argument "callback" (and hides first argument "error"):
async.waterfall([
function(callback) {
client.executeAsPrepared(select,
[param],
callback
);
},
function(result, callback) {
...
}], ...);
I got error because in Client.prototype._executeOnConnection callback called with 2 result args:
callback(err, result1, result2);
Why? Refer to documentation:
"Callback should take two arguments err and result."

Didn't look into this too much but could this be similar to issue #85?

Perhaps result2 is actually the retryCount like in the execute function. The execute function also returns 3 parameters even though the documentation only states that it returns err and result.

It's undefined. I can't find any use of result2 in code.
