integers, not a sequence of Unicode code points or using other encoding
scheme that does not preserve ordering.

Update `validate_abstract_methods` in `test_collections.py`
The test for missing abstract methods in `validate_abstract_methods` incorrectly attempted to instantiate the generated class `C` with an argument (`C(name)`), which always raises a `TypeError: C() takes no arguments`. Although the test originally passes, it passes for the wrong reason.
This change makes the test correctly validate the enforcement of abstract methods in ABCs.

fix potential hang.
It can happen that the child crashes right in the beginning for whatever reason. In this case, the parent will hang when writing into the pipe, because the child fd is not closed yet.
The normal pattern is to close the child fds right after the child proc is forked/executed/spawned, so when the child dies, then also the pipes will be closed, and there will be no hang (the parent gets SIGPIPE instead).

The OpenSSL and HACL* implementations of HMAC single-shot
digest computation reject keys whose length exceeds `INT_MAX`
and `UINT32_MAX` respectively. The OpenSSL implementation
also rejects messages whose length exceed `INT_MAX`.
Using such keys in `hmac.digest` previously raised an `OverflowError`
which was propagated to the caller. This commit mitigates this case by
making `hmac.digest` fall back to HMAC's pure Python implementation
which accepts arbitrary large keys or messages.
This change only affects the top-level entrypoint `hmac.digest`, leaving
`_hashopenssl.hmac_digest` and `_hmac.compute_digest` untouched.

gh-138813: Fix mutable default kwargs={} in multiprocessing BaseProcess and DummyProcess to use None (GH-138814)
* gh-138813: Default `BaseProcess` `kwargs` to `None` (GH-138814)
Set `BaseProcess.__init__(..., kwargs=None)` and initialize `kwargs` with
`dict(kwargs) if kwargs else {}`. This avoids a shared mutable default and
matches threading.Thread behavior.
* DummyProcess kwargs=None (which threading.Thread accepts properly)

gh-126631: gh-137996: fix pre-loading of `__main__`
The `main_path` parameter was renamed `init_main_from_name`, update the
forkserver code accordingly. This was leading to slower startup times when people
were trying to preload the main module.
