+ * 1.3.x, which does not use xhr object's onreadystatehandler at all - instead,
+ * it polls the object for completion with setInterval. Dispite the direct
+ * motivation, there is nothing jQuery-specific in this file, so it can be used
+ * in any environment where the ajax implementation depends on setInterval or
