+// test bug 1312774.
+// Create 6 (=network.http.max-persistent-connections-per-server)
+// common Http requests and 2 urgent-start Http requests to a single
+// host and path, in parallel.
+// Let all the requests unanswered by the server handler. (process them
+// async and don't finish)
+// The first 6 pending common requests will fill the limit for per-server
+// parallelism.
+// But the two urgent requests must reach the server despite those 6 common
+// pending requests.
+// The server handler doesn't let the test finish until all 8 expected requests
+// arrive.
+// Note: if the urgent request handling is broken (the urgent-marked requests
+// get blocked by queuing) this test will time out
