I've now made the Curl_expire() conditional so that it won't get called unless
it needs to tell another handle than the current one - which we need to do
because it has to act on incoming data without its socket getting any traffic
- and I now set TCP_NODELAY unconditionally for HTTP/2 sockets.
Both commits were just pushed to git.
I'm now seeing about 428MB/sec speeds on my localhost for a single-stream
transfer getting an 8GB file over HTTPS+nghttpd.
Downloading HTTP 1.1 from a localhost Apache gets me about 550MB/sec.
