[3.9] [3.10] gh-91607: Fix several test_concurrent_futures tests to actually test what they claim (GH-91600) (GH-91612) (#91617)

* 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.

gh-91421: Use constant value check during runtime (GH-91422) (GH-91493)

The left-hand side expression of the if-check can be converted to a
constant by the compiler, but the addition on the right-hand side is
performed during runtime.

Move the addition from the right-hand side to the left-hand side by
turning it into a subtraction there. Since the values are known to
be large enough to not turn negative, this is a safe operation.

Prevents a very unlikely integer overflow on 32 bit systems.

Fixes GH-91421.

bpo-47235: Note where a typo is intentional in code. (GH-32348)

People keep popping up reporting these as typos in the docs despite
being described as typos in the surrounding text.  Hopefully a comment
on the line itself makes it more obvious?

Arguably some of the typo examples are not using the "right" typo as the
"assret" one in particular is now detected by default due to how common
it was in actual code.  But I don't want to to typo chasing by changing
these examples to be other not yet auto-detected typos as they still
illustrate the point well enough.

[3.9] Document func parameter of locale.atof (GH-18183) (GH-32261)

The second parameter (named `func`) has been present since the `locale`
module was introduced in eef1d4e8b1, but has never been documented.

This commit updates the documentation for `locale.atof` to clarify the
behavior of the function and how the `func` parameter is used.

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..

bpo-42369: Fix thread safety of zipfile._SharedFile.tell (GH-26974)

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.
