purpose of the observableRun method

Hi Steven,

I am struggling to understand the purpose of the observableRun method especially in context of using AJAX methods.

Here is an extract from your IO examples:

linb.Thread.observableRun(function(threadid){
                            linb.Ajax(linbService,hash, onOK, onFail,threadid).start();
                        });

What is the advantage of using the observableRun method?

It would be great if you could address this topic in a tutorial (i.e about threads).

With best regards,

Ludwig

"observableRun" will add a transparent div on the top of DOM(User can't click other control during asysc ajax process), and change cursor to "wait" status(User can observe that the  current application is busy), until the ajax process returns data.
