Using DataMapper, how can I delay a method I want to fire after creation?

[Skeyelab]

I am using DataMapper callbacks to call a method that imports user data from Zendesk when I create a "desk" object in my app. This is working great. However, importing the user data can take some time for some of the larger accounts I work with. Does anyone have any advice on how to call this callback via backburner? http://datamapper.org/docs/callbacks.html
