    Description

      see: https://codereview.qt-project.org/#change,67626 & tst_QCoreApplication::testDeferredDeleteFromAboutToBlock

      deletion doesn't work until the application exits, leading to massive memory leaks in e.g. QtWayland and xcb which both tie into the dispatcher's signals. probably third party code, too.
