 Replying to [comment:12 azaozz]:

 > The jQuery Callbacks() looks like a good candidate but is missing some
 key features like  priorities and namespaces. Considering it would be
 preferable to keep this API self-contained, perhaps we can settle for a
 simpler solution using few loops instead of trying to patch/extend
 Callbacks(). That would need less maintenance too.

 Callbacks does offer the .fired() method to test if a particular callback
 has been fired:  http://api.jquery.com/callbacks.fired/. Being able to
 tell specifically whether or not a particular callback or list of
 callbacks has fired would be useful. That doesn't solve the problem of
 actually being able to call one method before another, but I do think it's
 a worthwhile feature that should be added into whatever solution ends up
 being used.
