[issue6017] Dict fails to notice addition and deletion of keys during iteration

[Benjamin Peterson]

Benjamin Peterson <benjamin at python.org> added the comment:

This is correct; dict iterators check to see if the size of the dict is
different. However, fixing this problem would require tracking dict
contents during iteration. That strikes me as too inefficient and too
much code for this little case.
