This also causes problems when the QGuiApplication is created in a

Timers cannot be stopped from another thread ". There are also reports
that this can cause crashes [3][4].
ooooh ya, this sounds familiar. I have seen this before when I was
working on wasm pthread support and trying out emscripten's
PROXY_TO_PTHREAD, which moves the main() function to a thread to leave
the main browser thread to do other things so it never blocks.
