This starts the process. Users who don't specify their own start method
and use the default on platforms where it is 'fork' will see a
DeprecationWarning upon multiprocessing.Pool() construction or upon
multiprocessing.Process.start() or concurrent.futures.ProcessPool use.

Fix backslashes in AF_PIPE (#88355)
The correct syntax for AF_PIPE addresses is `\\.\pipe\blahblah`, not `\.\pipe{blahblah}`, but the syntax markup messed up the backslashes.
API members documented in sphinx have an object name, which allow the
documentation to be linked from other projects. Sphinx calculates the
object name by prefixing the current module name to the directive
argument, e.g:
.. module:: foo
.. function:: bar.baz
becomes foo.bar.baz. Since these anchors aren't displayed in the
documentation, some mistakes have crept in, namely the Python stdlib
documentation currently contains the objects:
* asyncio.asyncio.subprocess.DEVNULL
* asyncio.asyncio.subprocess.PIPE
* asyncio.asyncio.subprocess.STDOUT
* asyncio.asyncio.subprocess.Process
* multiprocessing.sharedctypes.multiprocessing.Manager
* xml.etree.ElementTree.xml.etree.ElementInclude
This commit fixes this by making use of the :module: option which
without an argument makes sphinx take the directive argument as is
for the object name (avoiding the prefixing of the current module
name that led to these broken object names).

Add an optional keyword 'shutdown_timeout' parameter to the
multiprocessing.BaseManager constructor. Kill the process if
terminate() takes longer than the timeout.
Multiprocessing tests pass test.support.SHORT_TIMEOUT
to BaseManager.shutdown_timeout.
For threads, and for multiprocessing, it's always been the case that ``args=list`` works fine when passed to ``Process()`` or ``Thread()``, and such code is common in the wild. But, according to the docs, only a tuple can be used. This brings the docs into synch with reality.

This addresses [bpo-45554]() by expanding the `exitcode` documentation to also describe what `exitcode` will be in cases of normal termination, `sys.exit()` called, and on uncaught exceptions.

Up until now, the `multiprocessing.pool.ThreadPool` class has gone
undocumented, despite being a public class in multiprocessing that is
included in `multiprocessing.pool.__all__`.
Sphinx 3 requires to refer to terms with the exact case.
For example, fix the Sphinx 3 warning:
Doc/library/pkgutil.rst:71: WARNING: term Loader not found in case
sensitive match.made a reference to loader instead.
Since 3.7 `successful` raises a `ValueError` as explained in the next text block from the documentation:
_Changed in version 3.7: If the result is not ready, ValueError is raised instead of AssertionError._
No issue associated with this PR.
Should be backported in 3.7 and 3.8.
