Your timeout function

setTimeout(self.timeoutHandler, 750);

may be causing memory leak. Although the success: callback is able to exit after finished, there may not be an empty context in a setTimeout callback causing a circular loop. Youl should take out the anonymous function to end up something like this:

var pManager = new PageManager ();
pManager.timeoutHandler();

function PageManager () {
var ret  = (function(self) { 
    return function() { self.timeoutHandler(); };
})(this);

this.timeoutHandler = function () {
    $.ajax ({
        url: '/echo/json/',
        type: 'post',
        cache: false,
        success: function (data) {
            setTimeout (ret, 750);
        }
    });
};
}

This should only call back once.
