test more reliable (= fail more often on Windows with HPET enabled).

test_timeout_rounding() on Windows XP buildbots.

to reflect the fact that they only accept positional-only arguments.

now register both filenames in the exception on failure.
This required adding new C API functions allowing OSError exceptions
to reference two filenames instead of one.

Documented the AbstractEventLoopPolicy interface explicitly and explained the
relation between the global loop & policy access functions. Added an initial
section that explains the connections in general terms. Documented missing XXX
methods.

The decoder does not support partial decoding yet for this code page.

The new syntax is highly human readable while still preventing false
positives.  The syntax also extends Python syntax to denote "self" and
positional-only parameters, allowing inspect.Signature objects to be
totally accurate for all supported builtins in Python 3.4.

Process and Popen objects

This is more RFC compliant (see issue) and fixes a problem with
signature verifiers rejecting the part when signed.  There is some
amount of backward compatibility concern here since it changes
the output, but the RFC issue coupled with fixing the problem
with signature verifiers seems worth the small risk of breaking
code that depends on the current incorrect output.

Include the mention of ResourceWarning being displayed by default by the test runner.

Issue #20540: Fix a performance regression (vs. Python 3.2) when layering a multiprocessing Connection over a TCP socket.
For small payloads, Nagle's algorithm would introduce idle delays before the entire transmission of a message.
