--- Comment #3 from Joseph Pecoraro <joepeck at webkit.org> ---
The Web Inspector frontend is only told about one requestWillBeSent from the backend (followed up by its responseReceived/dataReceived/loadingFinished updates):

    backend: {
        "method": "Network.requestWillBeSent",
        "params": {
            "requestId": "0.15",
            "frameId": "0.1",
            "loaderId": "0.5",
            "documentURL": "file:///Volumes/Data/Users/pecoraro/Desktop/cache-bug.html",
            "request": {
                "url": "http://api.randomuser.me/",
                "method": "GET",
                "headers": {
                    "Accept": "application/json, text/javascript, */*; q=0.01",
                    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11) AppleWebKit/602.1.1 (KHTML, like Gecko) Version/9.0 Safari/601.1.41",
                    "Cache-Control": "max-age=0"
                }
            },
            "timestamp": 0.045744980983727146,
            "initiator": { ... }
            "type": "XHR"
        }
    }

So from the appearance of the frontend only 1 request was sent. That may in fact be what the engine is doing. The frontend should at least show that >1 XHR was initiated for the same URL, even if only 1 request was actually sent and they are sharing it. It would likely share a lot of timing information.
