When only the main thread exists, no GIL operations are needed. This is a
common situation (most Python programs do not use threads), and the lock
operations slow the interpreter down a bit. Therefore, the lock is not

The :mod:`getopt` module is a parser for command line options whose API is
designed to be familiar to users of the C :c:func:`getopt` function. Users who
are unfamiliar with the C :c:func:`getopt` function or who would like to write
:exc:`UnsupportedOperation`.

:class:`BufferedRWPair` does not attempt to synchronize accesses to
its underlying raw streams. You should not pass it the same object
as reader and writer; use :class:`BufferedRandom` instead.

:func:`eval`, use of this function may open its users to a security risk.
While the function only binds to a socket on ``localhost``, and so does
not accept connections from remote machines, there are scenarios where
:class:`~logging.Formatter` can present exception tracebacks in an expanded or
condensed format.

+ Due to the use of :func:`eval` as described above, there are
potential security risks which result from using the :func:`listen` to send
and receive configurations via sockets. The risks are limited to where
multiple users with no mutual trust run code on the same machine; see the

+ On Mac OS X, :func:`getgroups` behavior differs somewhat from
other Unix platforms. If the Python interpreter was built with a
deployment target of :const:`10.5` or earlier, :func:`getgroups` returns
the list of effective group ids associated with the current user process;
automatically closed when they are garbage-collected.

:meth:`close()` releases the resource associated with a connection but
does not necessarily close the connection immediately. If you want
to close the connection in a timely fashion, call :meth:`shutdown()`
