No, clearly not an acceptable fix. Though, this may be a sign that accumulating
more data on the socket reduce CPU usage (could be double parsing or other
common bugs). This small CPU increase may also mean latency is actually better
in 1.0+. Better measure both, and see if it's worth calling this a regression.
