* Fix test_concurrent_futures to actually test what it says.
Many ProcessPoolExecutor based tests were ignoring the mp_context
and using the default instead. This meant we lacked proper test
coverage of all of them.
Also removes the old _prime_executor() worker delay seeding code
as it appears to have no point and causes 20-30 seconds extra
latency on this already long test. It also interfered with some
of the refactoring to fix the above to not needlessly create their
own executor when setUp has already created an appropriate one.
* Don't import the name from multiprocessing directly to avoid confusion.

Replace the child process `typeperf.exe` with a daemon thread that reads the performance counters directly. This prevents the issues that arise from inherited handles in grandchild processes (see issue37531 for discussion).
We only use the load tracker when running tests in multiprocess mode. This prevents inadvertent interactions with tests expecting a single threaded environment. Displaying load is really only helpful for buildbots running in multiprocess mode anyway..

Inputs >= 4GiB to `binascii.crc32(...)` when compiled to use the zlib
crc32 implementation (the norm on POSIX) no longer return the wrong
result.

The `_SharedFile` tracks its own virtual position into the file as
`self._pos` and updates it after reading or seeking. `tell()` should
return this position instead of calling into the underlying file object,
since if multiple `_SharedFile` instances are being used concurrently on
the same file, another one may have moved the real file position.
Additionally, calling into the underlying `tell` may expose thread
safety issues in the underlying file object because it was called
without taking the lock.

Also made modes containing 'a' or 'x' act the same as a mode containing 'w' when argument is '-'
(so 'a'/'x' return sys.stdout like 'w', and 'ab'/'xb' return sys.stdout.buffer like 'wb').

We were using os_helper, which doesn't exist on 3.9. This wasn't
caught because the test is only run as root. I confirmed that when
run as root, the test previously failed and now passes.
Add the following info to test.pythoninfo:
* windows.ver: output of the shell "ver" command
* windows.version and windows.version_caption: output of the
"wmic os get Caption,Version /value" command.

* bpo-46913: test_hashlib skips _sha3 tests on UBSan (GH-31673)
If Python is built with UBSan, test_hashlib skips tests on the _sha3
extension which currently has undefined behaviors.
This change allows to run test_hashlib to check for new UBSan regression,
but the known _sha3 undefined behavior must be fixed.

Fix a bug in urllib.request.HTTPPasswordMgr.find_user_password() and
urllib.request.HTTPPasswordMgrWithPriorAuth.is_authenticated() which
allowed to bypass authorization. For example, access to URI "example.org/foobar"
was allowed if the user was authorized for URI "example.org/foo".

Curly brackets were never allowed in namespace URIs
according to RFC 3986, and so-called namespace-validating
XML parsers have the right to reject them a invalid URIs.
libexpat >=2.4.5 has become strcter in that regard due to
related security issues; with ET.XML instantiating a
namespace-aware parser under the hood, this test has no
future in CPython.
