Hi,

 

I have just found a code segment of ajax may cause a memory leak:

 

try {
   var oldAbort = xhr.abort;
   xhr.abort = function() {
    if ( xhr ) {
     oldAbort.call( xhr );
    }

    onreadystatechange( "abort" );
   };
  } catch(e) { }

 

oldAbort and xhr seems a circular reference.

 

I'm using sIEve-0.0.8 on IE8, you may like to see attached screenshots.
