    Description

      running the asyncio miminal example which loads a qml file, the python process memory usage increase 10M per seconds, while there is nothing running in the backends.

      here is the screen capture videos

      it will collapse until running out of memories i guess

      here is the example i running, 

      the qml file it loads is just a simple window

      import QtQuick 2.15
      import QtQuick.Window 2.15
      
      Window {
       id: window
       width: 400
       height: 500
       visible: true
      }
      

      change the AsyncHelper to qasync, the memory usage is stable, not growing any more
