Description Antti Koivisto 2021-01-19 02:49:32 PST 
With HTTP/2 image loads can saturate the connection and cause the loading of more important resources to be delayed (https://blog.cloudflare.com/better-http-2-prioritization-for-a-faster-web/ for a pretty good analysis). We should do some scheduling in the network process.

I didn't check the EWS issues; might be something to fix before landing.
