Try to prevent this test from being flaky.  We might need a sleep in here
which isn't as bad as it sounds.  The close() *should* raise an exception,
so if it didn't we should give more time to sync and really raise it.

Let the O/S supply a port if none of the default ports can be used.
This should make the tests more robust at the expense of allowing
tests to be sloppier by not requiring them to cleanup after themselves.
(It will legitamitely help when running two test suites simultaneously
or if another process is already using one of the predefined ports.)

This will hopefully fix test_asynchat.

On some systems (e.g., Ubuntu on hppa) the flush()
doesn't (always) cause the exception, but the close() does.

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.

Backport of r60265.

Also removed three non-ASCII chars at start of file.

Fix issue #1303614, test67.py.

were not accepted.

Fixed bug #1915: Python compiles with --enable-unicode=no again. However several extension methods and modules do not work without unicode support.

- Issue #1336: fix a race condition in subprocess.Popen if the garbage

Fix for #1303614 and #1174712:
- __dict__ descriptor abuse for subclasses of built-in types
- subclassing from both ModuleType and another built-in types

create a new weakref to the object.

- Issue829951: In the smtplib module, SMTP.starttls() now complies with
  RFC 3207 and forgets any knowledge obtained from the server not obtained
  from the TLS negotiation itself.  Patch contributed by Bill Fenner.

  Fix a potential 'SystemError: NULL result without error'.
  NULL may be a valid return value from PyLong_AsVoidPtr.
Also move an older ctypes NEWS item in the correct category.

Fix 1698398:  Zipfile.printdir() crashed because the format string expected a tuple object of length six instead of a time.struct_time object.
