I ran your test in FF3.5, and I ended up seeing no log entry in about 1 of every 10 trials, although I saw the request every time in firebug. I changed your test around to use body onload instead, and it works fine every time I test it. Since the requests seem to be going through, signal.js is loading every time before signal is called, but logging probably is not (loaded much later than signal). If I change 'log' to 'alert' in your example, the problem doesn't persist. So, even if FF loads all of the scripts in head in the correct order, script tags in body can be loaded at any point of that process, thus creating the race condition. That's probably a bug in firefox then, as I can't think of why that behavior would be desirable.
