comments about why both calls to cyclic gc here can cause problems.

that will be the end of it.

isn't checked, and it *is* possible that a very large alloca() call is
made, e.g. when a large registry value is being read.  I don't know if
alloca() in that case returns NULL or returns a pointer pointing outside
the stack, and I don't want to know -- I've simply replaced all calls to
alloca() with either PyMem_Malloc() or PyString_FromStringAndSize(NULL,)
as appropriate, followed by a size check.  This addresses SF buf 851056.
Will backport to 2.3 next.

  This addresses most of the remaining semantic changes promised by
  PEP 237, except for repr() of a long, which still shows the trailing
  'L'.  The PEP appears to promise warnings for operations that
  changed semantics compared to Python 2.3, but this is not
  implemented; we've suffered through enough warnings related to
  hex/oct literals and I think it's best to be silent now.

* Refactor and neaten the code a bit.
* Rename union_update() to update().
* Improve the algorithms (making them a closer to sets.py).

* Add a better test for deepcopying.

* Add tests to show the __init__() function works like it does for list

* Have shallow copies of frozensets return self.  Add related test.

* Have frozenset(f) return f if f is already a frozenset. Add related test.

* Beefed-up some existing tests.

  by the function object or by the method object, the function
  object's attribute usually wins.  Christian Tismer pointed out that
  that this is really a mistake, because this only happens for special
  methods (like __reduce__) where the method object's version is
  really more appropriate than the function's attribute.  So from now
  on, all method attributes will have precedence over function
  attributes with the same name.
