<p>Common probe entry point. </p>
<p>This is the common main function of all probe processes that initializes all the stuff needed at probe runtime. This function also contains the main loop which listens for new request and in case the result was already evaluated (it is stored in the item cache) it replies to the request immediately. In the other case a new thread is spawned which takes care of the evaluation and reply. </p>
