  Clean-up and speed-up code by accessing numerator/denominator directly.  There's no reason to enforce readonliness

  News about recently fixed crashers:
  - A few crashers fixed: weakref_in_del.py (issue #1377858);
    loosing_dict_ref.py (issue #1303614, test67.py);
    borrowed_ref_[34].py (not in tracker).

  Use a PyDictObject again for the array type cache; retrieving items
  from the WeakValueDictionary was slower by nearly a factor of 3.

  To avoid leaks, weakref proxies for the array types are put into the
  cache dict, with weakref callbacks that removes the entries when the
  type goes away.

  Replace Py_BuildValue with PyTuple_Pack because it is faster.
  Also add a missing DECREF.

  Invert the checks in get_[u]long and get_[u]longlong.  The intent was
  to not accept float types; the result was that integer-like objects
  were not accepted.

  Ported from release25-maint.

  Shorter pprint's for empty sets and frozensets.  Fix indentation of frozensets.  Add tests including two complex data structures.

  #1920: when considering a block starting by "while 0", the compiler optimized the
  whole construct away, even when an 'else' clause is present::

      while 0:
          print("no")
      else:
          print("yes")

  did not generate any code at all.

  Now the compiler emits the 'else' block, like it already does for 'if' statements.

  Will backport.

  Make the test more robust by trying to reconnect up to 3 times
  in case there were transient failures.  This will hopefully silence
  the buildbots for this test.  As we find other tests that have a problem,
  we can fix with a similar strategy assuming it is successful.  It worked
  on my box in a loop for 10+ runs where it would have an exception otherwise.

  r60277 | neal.norwitz | 2008-01-25 09:04:16 +0100 (Fri, 25 Jan 2008) | 4 lines

  Add prototypes to get the mathmodule.c to compile on OSF1 5.1 (Tru64)
  and eliminate a compiler warning in floatobject.c.  There might be
  a better way to go about this, but it should be good enough for now.
