Clearing your cache doesn't mean that the server is sending you the most recent file, because the server has it's own cache, and there's no way to force it to update until it's good and ready.

edit: To help with this issue, I've added a div to Mediawiki:clearyourcache with a custom class "checkJavascriptCache", and a line in the javascript: $('.checkJavascriptCache').css('background-color','yellow'); so I change the listed colour any time I want to watch for when the cache has updated. That way, if the colour of the div is still red, I know I'm not seeing my changes yet.
