You can simulate an Alfresco AJAX both sync and async as follows:

function myAlfrescoAjax(wsUrl, async) {
// wsUrl: string, the url of your webscript
// async: boolean, a false value simulates synchronous

    var simSync = {}; // define a local variable for simulation
    Alfresco.util.Ajax.request(
    {
    method : "GET",       
    url: Alfresco.constants.PROXY_URI + wsUrl,
        successCallback: {
            fn: function (response) {
                // insert code for succesful response
                if (!async) clearTimeout(simSync);  // resume execution  when ready (see below)
            },
            scope: this
        },
        failureMessage: "Server Error",
        execScripts: true
    });
// now immediately stop execution (if synchronous) with a timeout that takes longer than you ever expect the time the Ajax call will take
// note that this timer is killed on succes of the response function in the Ajax call
    if (!async) {
        simSync = setTimeout(function(){
        // insert code for the unexpected case the timer elapses fully
        }, 5000);
    }
    return
}
