title: Qt qml application increasing memory usage
body: <p>I created an application with Qt/QML, load a qml file with <code>QQuickView</code>, and with this use a <code>Loader</code> element for change the pages(gui) inside application, and works fine, but my problem is the increase of the program memory usage (the application starts with less of 100MB, and after 1 day, the size is about 500 MB or more), I originally write and update the  model of objects in Qml (javascript), but the application grows quickly, changing to create models with C++ objects, memory usage grows less but the problem is still not solved.</p>
  
  <p>My model can be updated continuously (even 1 time per second), but I don't believe that be the reason of memory rises.</p>
  
  <p>But with that problem come other strangers behaviors is with TableView when changes to that page, the memory rises even 10 MB, I try to free memory with <code>gc()</code>, but i don't get successful results, and in the change of page, the memory sometimes can rise by 1 MB.</p>
  
  <p>Note: I use a Qt 5.5, and msvc 2010.</p>
