Comment (by Daedalon):

 Here's a jQuery solution for confirming page close when any of the new
 post fields have been modified.

 {{{
 var requireCloseConfirmation = false;
 function confirmPageClose(){
         if ( requireCloseConfirmation ) {
                 return 'Are you sure you want to close this page? All
 changes will be lost.';
         }
 }
 jQuery('#postform input[type=text], #postform select, #postform
 textarea').change( function(){
         requireCloseConfirmation = true;
 });
 if( jQuery('#postform').length ){
         window.onbeforeunload = confirmPageClose;
 }
 }}}

 This is triggered only if any one of these text areas has been changed
 '''and''' it has lost focus at least once. In other words this protects
 from most accidental closings except when user has changed only one field
 without clicking outside it or otherwise moving focus away from it. This
 should catch the vast majority of cases.

 A timer-based script could cover even those that this does not. It would
 check every XX seconds if any of the fields are non-empty, and if, sets
 requireCloseConfirmation = true and terminates itself.
