As far as i understood the bottomline is the task to make an external
process fully modal to the window, yesno?
Aside that the NETWM spec probably SHOULD say that modal windows must not
receive input focus and mouse events and also not be closed, weird ideas:
a) add an eventfilter on the application to suck all input events (for
that window) so clicking apply etc. isn't possible and the window also
will not receive close events
b) intercept sigterm and reject it as long as you're waiting for the async
