You could put the returning values in a queue. To guarantee the order, 
you could send a counter that is increased with every request, return 
that counter value and use it for restore the order while processing the 
queue. Some basic functions to start with could look like this:

function synchronize(callback) {
    queue[queue.length] = callback;
    if(!blocking) {
        process();
    }
}

function process() {
    while(queue.length && !blocking) {
        var call = queue[0];
        queue = queue.slice(1);
        call();
    }
}
