...
* Decrease event loop latency by binding time.monotonic to loop.time directly
This is a small improvment to decrease event loop latency. While the goal is
is to reduce Bluetooth connection time latency, everything using asyncio
is a bit more responsive as a result.
* relo per comments
* fix too fast by adding resolution, ensure monotonic time is patchable by freezegun
* fix test that freezes time too late and has a race loop

Avoid subprocess memory copy when c library supports posix_spawn ( #87958 )

* use posix spawn on alpine
* Avoid subprocess memory copy when c library supports posix_spawn
By default python 3.10 will use the fork() which has to
copy all the memory of the parent process (in our case
this can be huge since Home Assistant core can use
hundreds of megabytes of RAM). By using posix_spawn
this is avoided.
In python 3.11 vfork will also be available
https://github.com/python/cpython/issues/80004#issuecomment-1093810689
https://github.com/python/cpython/pull/11671 but we won't
always be able to use it and posix_spawn is considered safer
https://bugzilla.kernel.org/show_bug.cgi?id=215813#c14
The subprocess library doesn't know about musl though
even though it supports posix_spawn https://git.musl-libc.org/cgit/musl/log/src/process/posix_spawn.c
so we have to teach it since it only has checks for glibc

Use PidfdChildWatcher by default when available ( #87951 )
...
This is a backport from cpython 3.12
https://docs.python.org/3/library/asyncio-policy.html
> PidfdChildWatcher is a “Goldilocks” child watcher implementation. It doesn’t require signals or threads, doesn’t interfere with any processes launched outside the event loop, and scales linearly with the number of subprocesses launched by the event loop. The main disadvantage is that pidfds are specific to Linux, and only work on recent (5.3+) kernels.
https://github.com/python/cpython/pull/98024
There are some additional fixes in cpython 3.12
in https://github.com/python/cpython/pull/94184
when there is no event loop running in the main thread
but this is not a problem we have

Make executor max_workers consistent between python versions ( #38821 )
...
The default on python 3.8 is for max_workers is significantly
lower than the default on python 3.7 which means we can get starved
for workers.
To determine a reasonable maximum, the maximum was increased to large
number on 5 production instances.
The number of worker threads created during startup that were
needed to avoid waiting for a thread:
HOU 1 - 71
HOU 2 - 48
OGG 1 - 60
OGG 2 - 68
OGG 3 - 64
This lead to a selection of 64 as it was reliable in all cases
and did not have a significant memory impact
