#! Add the new window just below the topmost window. Why?
#! So that if the new window doesn't actually receive focus
#! (eg, we're using focus follows mouse and the mouse is not
#! in the new window when it appears) Factor doesn't get
#! confused and send workspace operations to the new window,
#! etc.
