then a copy-on-write scalar drops its PV buffer (if any) and becomes
SvPOK_off rather than making a copy. (Used where this scalar is about to be
set to some other value.) In addition, the C<flags> parameter gets passed to

+C<sv_unref_flags()> when unreffing. C<sv_force_normal> calls this function
with flags set to 0.
