+Subject: [PATCH] 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
