On staging armhf (the click test app is armhf) it's still pretty much as described in comment #15. It is possible to get the "edit comnfig" to hang, and after the fake stale lock file one will need a second start attempt so that app really starts.
So this is with Qt 5.6.1 which includes all the patches tried before and some more. It probably fixes Antti's issue and some others, but not Michael's test app at least.
Maybe the test case could be submitted upstream stating it'd be nice to get a fix to 5.6 series? (giving partial assigning to Michael to note this) There are also no newer commits that seem meaningful to qlockfile.cpp or qlockfile_unix.cpp, so it should be reproducable on even dev.
