Overview

we only use this for buffering the tiniest responses (which are already strings in memory and a handful of bytes).

"HTTP", "/1.1 "
"HTTP/1.1 100 Continue\r\n\r\n"
"100 Continue\r\n\r\nHTTP/1.1 "

This is very, very rarely triggered. 1) check_client_connection is enabled 2) the client sent an “Expect: 100-continue” header

Most output buffering goes through the normal Yahns::Wbuf class which uses a temporary file as a buffer (suitable for sendfile())
