Kernel response buffering

[Tratcher]

Http.Sys supports internal response buffering for better response performance. WebSockets already enables this by default. However, enabling this prevents the developer from doing multiple concurrent writes.

Consider enabling this by default, and allowing it to be configured per server and/or per-request.
