The intent is to be able to do things like:

	backend b1 {
		set backend.host = "fs.freebsd.dk";
		set backend.port = "82";
	}
	backend b2 {
		set backend.host = "fs.freebsd.dk";
		set backend.port = "81";
	}
	backend b3 {
		set backend.host = "fs.freebsd.dk";
		set backend.port = "80";
	}

	sub vcl_recv {
		remove req.http.cookie;
		if (req.restarts == 0) {
			set req.backend = b1;
		} else if (req.restarts == 1) {
			set req.backend = b2;
		} else {
			set req.backend = b3;
		}
	}

	sub vcl_fetch {
		if (obj.status != 200) {
			restart;
		}
	}

cache_fetch.c now reports the response code or a indicative negative
status for failed requests to the backend code.

Any timeouts, keepalives or other overhead processing of health codes
should happen in a thread in the backend handling.

"vqueue.h" which is based on FreeBSD's <sys/queue.h> with the debugging
taken out and a "V" prefix added to everything.
