Async postbacks to the same target are cancelled

Question

I'm using manually initiated postbacks to do some magic in a demonstration I'm making.

This is the function I'm using to initiate them:

function doPostBackAsync(eventName, eventArgs) {
    var prm = Sys.WebForms.PageRequestManager.getInstance();
    prm.beginAsyncPostBack(null, eventName, eventArgs, false);
}

The problem I am having is that if the request is not completed before the user triggers a new postback, the request is cancelled.

The only solution I've thought of is to add a random value to the query string, but in order to do so I would have to abandon using this function and likely create an ajax request, thus requiring significant rework to achieve the functionality I've developed thus far.

Any ideas?

After reading this question it is my impression that this is a limitation of the framework I'm trying to leverage.
