setTimout on 0 is also very useful in the pattern of setting up a deferred promise, which you want to return right away:
myObject.prototype.myMethodDeferred = function() {
var deferredObject = $.Deferred();
var that = this; // Because setTimeout won't work right with this
setTimeout(function() {
return myMethodActualWork.call(that, deferredObject);
}, 0);
return deferredObject.promise();
}
