I personally look at what is being done, I will ususally use an asyc request to ensure that the UI doesn't block, however, I MAY during the course of that request disable the UI of my application.

A prime example of this is in an application that I built with a "search" button. Once the search was triggered as an async request I would disable the button until the response came back, effectivly limiting the ability for the user to spawn a second asyc request.

Doing this, at least I can prevent the need for priorites, granted this only works if you can in an easy to do way, limit your users to one action at a time.
