Some socket tests related to sending file descriptors cause a file descriptor leak on macOS, all of them tests that send one or more descriptors than cannot be received on the read end. This appears to be a platform bug.
This PR skips those tests when doing a refleak test run to avoid hiding other problems.
I believe I added this while chasing some performance of hash functions
when I first created hashlib. It hasn't been used since, is frankly
trivial, and not a test.
* gh-112529: Use GC heaps for GC allocations in free-threaded builds
The free-threaded build's garbage collector implementation will need to
find GC objects by traversing mimalloc heaps. This hooks up the
allocation calls with the correct heaps by using a thread-local
"current_obj_heap" variable.
* Refactor out setting heap based on type
The GH-93000 change set inadvertently caused a sentence in re.compile()
documentation to refer to details that no longer followed. Correct this
with a link to the Flags sub-subsection.

Use `_make_child_entry()` rather than `_make_child_relpath()` to retrieve
path objects for directories to visit. This saves the allocation of one
path object per directory in user subclasses of `PathBase`, and avoids a
second loop.
This trick does not apply when walking top-down, because users can affect
the walk by modifying *dirnames* in-place.
A side effect of this change is that, in bottom-up mode, subdirectories of
each directory are visited in reverse order, and that this order doesn't
match that of the names in *dirnames*. I suspect this is fine as the
order is arbitrary anyway.
Allow `os.PathLike` objects to be passed as patterns to `pathlib.Path.glob()` and `rglob()`. (It's already possible to use them in `PurePath.match()`)
While we're in the area:
- Allow empty glob patterns in `PathBase` (but not `Path`)
- Speed up globbing in `PathBase` by generating paths with trailing slashes only as a final step, rather than for every intermediate directory.
- Simplify and speed up handling of rare patterns involving both `**` and `..` segments.
Use a ring buffer instead of a Python list in order to simplify the
process of making queue.SimpleQueue thread-safe in free-threaded
builds. The ring buffer implementation has no places where critical
sections may be released.
* gh-104522: Fix test_subprocess failure when build Python in the root home directory
EPERM is raised when setreuid() fails.
EACCES is set in execve() when the test user has not access to sys.executable.
gh-113205: test_multiprocessing.test_terminate: Test the API works on threadpools
Threads can't be forced to terminate (without potentially corrupting too much
state), so the expected behaviour of `ThreadPool.terminate` is to wait for
the currently executing tasks to finish.
The entire test was skipped in GH-110848 (0e9c364f4a).
Instead of skipping it entirely, we should ensure the API eventually succeeds:
use a shorter timeout.
For the record: on my machine, when the test is un-skipped, the task manages to
start in about 1.5% cases.
Only set filename to cwd if it was caused by failed chdir(cwd).
_fork_exec() now returns "noexec:chdir" for failed chdir(cwd).
