Purpose of this exercise: invoke queryClose() without actually closing the
windows, because
- queryClose() may contain session management code, so it must be invoked
- actually closing windows may quit the application - cf.
QGuiApplication::quitOnLastWindowClosed()
- quitting the application and thus closing the session manager connection
violates the X11 XSMP protocol.
The exact requirement of XSMP that would be broken is,
in the description of the client's state machine:
save-yourself-done: (changing state is forbidden)
Closing the session manager connection causes a state change.
Worst of all, that is a real problem with ksmserver - it will not save
applications that quit on their own in state save-yourself-done.
