It seems that beforeload events are always fired twice (at least on <embeds>) when plugins are disabled in Safari's preferences. I assumed that was the same as having no plugins installed, but it's not. Evaluation of things like event.target.offsetWidth or event.target.parentNode.toString() if the parent is an <object> create a 2nd beforeload dispatch on event.target within the handler, but otherwise a 2nd beforeload is still fired after the first has been handled.

Anyway I cannot reproduce the first example in my comment #11 if plugins are enabled, so this is not quite a real-life example, but still a valid test case to keep in mind to make sure beforeload dispatch is logically implemented.
