Right, I've already looked at XMLHttpRequest#abort(). It wouldn't be a "clean"
solution anyway.

That's what I've already done - Wicket schedules and executes AjaxLink action
(it does not wait for other lazy panels - so far, so good ), but then (already
during handling new ajax request) Wicket throws exception. Isn't it a Wicket
bug?
