At first glance things look OK on 4.0, 4.1, 5.0 and 5.1:

    varnishtest "purge+restart should miss"

    server s1 {
        rxreq
        txresp -body first

        rxreq
        txresp -body second
    } -start

    varnish v1 -vcl+backend {
        sub vcl_recv {
            if (req.method == "PURGE") {
                return (purge);
            }
        }

        sub vcl_purge {
            set req.method = "GET";
            return (restart);
        }
    } -start

    client c1 {
        txreq
        rxresp
        expect resp.body == first

        txreq -req PURGE
        rxresp
        expect resp.body == second
    } -run

I will try a more involved test later on.
