So I've built 7.74 with QUICHE and found out this:
- It looks like there are no problems now, no interruptions, not even after
hundred requests or so.
- If I introduce some artificial packet loss on the server, i.e. 1% (via
netem tool), eventually it hangs. ( I.e. HTTP2 goes well despite the loss.)
