Per-screen, you mean?  This iteration stores the global pointer window in a
qdata on the GdkScreen; there doesn't seem to be anywhere I can add a member to
a struct, unfortunately.

No, it does happen fairly often e.g. in menus or scrollbars, where a no-window
widget gets Gtk+ grab.  But it won't leak events, because the no-window widget
isn't expecting enter/leave events anyway.
