  Tests for bin() builtin.  These need to get merged into py3k, which has no tests for bin.

  Improve the implementation of itertools.product()

  * Fix-up issues pointed-out by Neal Norwitz.
  * Add extensive comments.
  * The lz->result variable is now a tuple instead of a list.
  * Use fast macro getitem/setitem calls so most code is in-line.
  * Re-use the result tuple if available (modify in-place instead of copy).

  Issue 1881. Increased the stack limit from 500 to 1500. Also added
  a test for this (and because of this test you'll see in stderr a
  message that parser.c sends before raising MemoryError).
  Thanks Ralf Schmitt.

  Issue 1781. Now ConfigParser.add_section does not let you add a
  DEFAULT section any more, because it duplicated sections with
  the rest of the machinery. Thanks Tim Lesher and Manuel Kaufmann.
