In src/webserver/Webserver.Incoming.cc you have an ad-hoc HTTP parser that internally buffers partial request data and does some questionable things like recursing on each request header line. Consider using a finite state machine parser for HTTP like this one [1] or this one [2], which will reduce your overhead, and help you push the buffering and eof problems back up to the main event loop code.
