So, I think that the first version of the patch, when it got a big
chunk of data, would just flush whatever was already in the buffer and
then send the rest without copying.

The current version, as I
understand it, only does that if the buffer is empty; otherwise, it
copies data as much data as it can into the partially-filled buffer.
