Test that the stacklevel is handled correctly.

class to that reusing the functionality in test_structmembers.py doesn't rerun
the tests from test_warnings.py.

tests in those who need the network, and that who doesn't.

\begin{methoddesc}[NNTP]{...}

where

\ifx#1\@undefined ended up comparing N and N, therefore executing
the true part of the conditional, blowing up at \@undefined.

  patch taken from http://bugs.debian.org/416934.

Two (test_array and test_descr) were bug IMO; the third (copy_reg)
is a work-around which recognizes that object.__init__() doesn't do
anything.

one of the test locales cannot be set.

locale changed but not used during the function call it was recreated during.

The test in this checkin is untested (OS X does not have the proper locale
support for me to test), although the fix for the bug this deals with
was tested by the OP (#1290505).  Once the buildbots verify the test at least
doesn't fail it becomes a backport candidate.

If MSVCCompiler.initialize() was called multiple times, the path
would get duplicated.  On Windows, this is a problem because the
path is limited to 4k.  There's no benefit in adding a path multiple
times, so prevent that from occuring.  We also normalize the path
before checking for duplicates so things like /a and /a/ won't both
be stored.

Will backport.

returned by python-config if Python was built with --enable-shared
because that prevented the shared library from being used.

the 2.5.0 release.

instantiating the class. Docs and tests are updated.

test_telnetlib.py with a basic test and timeout ones.
Docs are also updated.

the C lib's clock() is used, but it must be divided by CLOCKS_PER_SEC
as for the POSIX implementation (thanks to #pypy).
