[Greasemonkey] setTimeout() problems

[A. Alfred Ayache]

Try this:

   var arr = new Array("foo", "bar", "baz");
   var i = 0;
   function tLoop() {
     alert(arr[i]);
     if (++i < arr.length) {
       window.setTimeout(tLoop, 1000);
     }
   }

The way you've got it set up below seems to make the timeouts step on each 
other, no?
