this should be fixed.
A method which comes from trait should be always copied before
installing into behavior.
Otherwise, super sends won't work properly, as well as you may end up
with a mess,
where trait holding a reference to the non-existing behavior (added
then removed) , because
installing a method into method dict always changes its methodClass.
