I guess it's highly non-deterministic.  If the new strings happen to
take a previously-dummy entry of the interned strings dict, then after
they die the entry is dummy again and we don't have an extra refcount.
But if they take a fresh entry, then the dummy they become afterwards
counts for one ref.


A bientot,

Armin.
