I am missing something here. gb_sets (nor sets, ordsets, rbsets) does not
make a copy of the data which is put into the set. All that is copied is
enough of the *tree* to insert the new element. There is no need to copy the
new data as it is kept within the same process. Only ets makes a copy of the
data.
