-Subject: Stop unloading plugins in QPluginLoader and QFactoryLoader
-
-QPluginLoader hasn't unloaded in its destructor since Qt 5.0, but we
-missed the equivalent code in QFactoryLoader (which bypasses
-QPluginLoader). Besides, QPluginLoader::unload() was still doing
-unloading, which it won't anymore.
-
-Not unloading plugins is Qt's policy, as decided during the 5.0
-development process and reaffirmed now in 5.6. This is due to static
-data in plugins leaking out and remaining in use past the unloading of
-the plugin, causing crashes.
-
-This does not affect QLibrary and QLibrary::unload(). Those are meant
-for non-Qt loadable modules, so unloading them may be safe.
-
-Task-number: QTBUG-49061
-Discussed-on: http://lists.qt-project.org/pipermail/development/2015-November/023681.html
