The behavior is actually imposed by X-isms in GDK/GTK+, not more than one
target per selection can be on the fly, selection requests on the low-level
work by 1) emitting a GdkEventSelection and 2) the affected widget calling
gdk_property_change for the selection atom.

Newer requests should be cancelling previous ones, which I realize we don't
always do on all paths where gdk_wayland_selection_check_write() is called. 

More patches coming, testing appreciated, although I'll try too with your
weston hack.
