    Description

      Browsing QFileSystemModel in treeview uses huge amount of memory in short time. Browsing folders consumes memory easily 500-1000MB in one minute. See screenshot. At the end model is reseted (deleted and created new). Test attached application and analyse with XCode Instruments.
