the documented behavior: the function passed to the onerror()
  handler can now also be os.listdir.

got lost???]

put everything in the tuple in caps to use str.upper() instead of str.lower().

they are used

expected to write their own.  A NULL "object" must not be passed to
the visit callback.  A non-zero return from a visit proc isn't
necessarily an error return (and it doesn't matter to the tp_traverse
code *what* it might signify, their only job is to return it).

module that is removed for testing "import" lines.  Originally deleted the
entry from sys.modules and then just let other code that needed it to import it
again.  Problem with this solution is that it lead to code that had already
imported the module in question to have their own reference to a new copy of
the module in question that new code couldn't reach.  This lead to a failure in
test_strptime since it monkey-patched the 'time' module it had a reference to
while _strptime had its own reference to another copy of 'time' from being
imported by test___all__ that it was using for a calculation.

Also moved the testing code out of the PthFile class and into the actual test
class.  This was to stop using 'assert' which is useless with a -O execution.

a non-standard protocol and on a lower port than the tcp/udp entries,
which breaks the assumption that there will only be one service by a
given name on a given port when no protocol is specified.

Previous versions of this code have had other problems as a result of
different service definitions amongst common platforms.  As this platform
has an extra, unexpected, service entry, I've special cased the platform
rather than re-order the list of services checked to highlight the pitfall.

Removed debugging print statements from TimedRotatingFileHandler, and sorted list returned by glob.glob() (SF #987166)

I don't agree it had a bug (see the report), so this is *not* a candidate
for backporting, but the docs were confusing and the Queue implementation
was old enough to vote.

Rewrote put/put_nowait/get/get_nowait from scratch, to use a pair of
Conditions (not_full and not_empty), sharing a common mutex.  The code
is 1/4 the size now, and 6.25x easier to understand.  For blocking
with timeout, we also get to reuse (indirectly) the tedious timeout
code from threading.Condition.  The Full and Empty exceptions raised
by non-blocking calls are now easy (instead of nearly impossible) to
explain truthfully:  Full is raised if and only if the Queue truly
is full when the non-blocking put call checks the queue size, and
similarly for Empty versus non-blocking get.

What I don't know is whether the new implementation is slower (or
faster) than the old one.  I don't really care.  Anyone who cares
a lot is encouraged to check that.

This is a derived patch, taking the opportunity to add some organization
to the now-large pile of datetime-related macros, and to factor out
tedious repeated text.

Also improved some clumsy wording in NEWS.
