[issue2778] set_swap_bodies is unsafe

[Adam Olsen]

Adam Olsen <rhamph at gmail.com> added the comment:

Revised again.  sets are only hashed after PyObject_Hash raises a TypeError.

This also fixes a regression in test_subclass_with_custom_hash.  Oddly,
it doesn't show up in trunk, but does when my previous patch is applied
to py3k.
