Gregory P. Smith cd71799c47 gh-159185: Fix marshalling of a set modified while its elements are marshalled (GH-159195) 
Marshalling a set element can run Python code (__buffer__, an audit
hook) which changes the set.  The number of elements was read before
the loop, so a set which grew was written past the end of the list and
one which shrank left NULL items in the list which was then sorted.
Raise RuntimeError("set changed size during iteration") instead.
