why does live() need to run a selection during intit?

outlined here: ​http://www.zachleat.com/web/2009/05/08/performance-caveat-with-jquery-selectors-and-live-events/

maybe consider enhancement for 1.4?

jQuery can't have fore-knowledge of what will happen against the jQuery set - if so then that would be quite impressive.

Instead we recommend that you use event delegation instead, like the following:

$("#someRootTable").click(function(e){
  $(e.target).closest("td.foo", this).each(function(){
     // Your code goes here.
  });
});
