constructor, when passed a single complex argument, returns the
argument unchanged.  This should be done only for the complex base
class; a complex subclass should of course cast the value to the
subclass in this case.

The fix also revealed a segfault in complex_getnewargs(): the argument
for the Py_BuildValue() format code "D" is the *address* of a
Py_complex struct, not the value.  (This corroborated by the API
documentation.)

I expect this needs to be backported to 2.2.3.

calling into Python from a C thread.

proto 2 pickle too.

assertRaises.  Fixed a repeated subtle bug in the inplace tests by
removing the possibilty that a self.fail() call could raise a
TypeError that the test catches by mistake.

Allow mixed-type __eq__ and __ne__ for Set objects.  This is messier than
I'd like because Set *also* implements __cmp__.  I know of one glitch now:
cmp(s, t) returns 0 now when s and t are both Sets and s == t, despite
that Set.__cmp__ unconditionally raises TypeError (and by intent).  The
rub is that __eq__ gets tried first, and the x.__eq__(y) True result
convinces Python that cmp(x, y) is 0 without even calling Set.__cmp__.

elements get displayed in undefined dict order.  Use a Set subclass
instead (which arranges to sort the elements for display).

  rarely needed, but can sometimes be useful to release objects
  referenced by the traceback held in sys.exc_info()[2].  (SF patch
  #693195.)  Thanks to Kevin Jacobs!

The PyIter_Check is already performed by PyObject_GetIter.

require -u network to run test_timeout since
it fails when not connected to a network.

        try: # ...
        except ImportError, why:
        except: # ...
All other changes are re-indenting/formatting.

Change setup.py to catch all exceptions.
  - Rename module if the exception was an ImportError
  - Only warn if the exception was any other error

Revert _iconv_codec to raising a RuntimeError.

the build, so I'm restoring it.  I'm not sure what Neal's intent was,
since the line following the one he removed was "REQN(i, 1)" so i is
obviously used. ;)

stuff, and changed 'property' to 'descriptor'.

the #ifdef HAVE_NCURSES_H: the same problem exists on OSX 10.1 with
a fink-installed curses (which uses curses.h as the include file name).
