[Qt-interest] How to stop threads started by QFileSystemModel (QFileInfoGatherer, QWindowsFileSystemWatcherEngine)?

[Niels Dekker - no return address]

Our code basically does:

  QFileSystemModel* fileSystemModel = new QFileSystemModel();
  treeView->setModel(fileSystemModel);

Within the constructor of QFileSystemModel, a thread is created 
('QFileInfoGatherer'). During the lifetime of fileSystemModel, some 
other threads are created, including 'QWindowsFileSystemWatcherEngine'. 
Unfortunately the destructor of QFileSystemModel doesn't delete those 
threads. Is that a bug?

Anyway, it appears that those threads cause a crash of our application, 
because they keep running, even when qApp is destructed and Qt's DLL's 
are unloaded. Is there a way to stop the threads created by 
QFileSystemModel?

Kind regards, Niels

P.S. This question is related to the thread I started two days ago, 
"QtGui4.dll and QtCore4.dll don't unload, when using QFileSystemModel!",

Thanks for all your feedback so far!
