  In PyNumber_ToBase, changed from an assert to returning an error when PyObject_Index() returns something other than an int or long.  It should never be possible to trigger this, as PyObject_Index checks to make sure it returns an int or long.

  Two new functions:

    * place_summary_first copies the regrtest summary to the front of the file
      making it easier to scan quickly for problems.

    * count_failures gets the actual count of the number of failing tests, not
      just a 1 (some failures) or 0 (no failures).

  Re-enable tests, they were failing since gc.collect() clears the various freelists.
  They still remain fragile.

  For example, a call to assertEqual currently does not make any allocation
  (which surprised me at first).
  But this can change when gc.collect also deletes the numerous "zombie frames"
  attached to each function.
