In the attached test case, I append two script elements to the head element during document load and console.log the number of elements loaded as each script element loads and at window.onload. I get the following on the console: results.json Resource interpreted as script but transferred with MIME type text/html. race.html:21 Number of loaded results: 1 race.html:25 Number of results at window.onload: 1 results.json Resource interpreted as script but transferred with MIME type text/html. race.html:21 Number of loaded results: 2 The last script element gets executed after window.onload. Unless I'm crazy, all the script elements should be executed before the onload event fires, no? I think it might be a race condition that happens to get regularly triggered by the large size of the script files (~15MB), but that's just a guess. I tested this in a WebKit nightly and Safari 4 on the Mac. Both have the same behavior.
