gh-142302: Fix mkstemp() documentation: clarify file descriptor inheritance behavior ( #142338 )
...
The documentation incorrectly stated that the file descriptor is not
inherited by child processes. In reality, the close-on-exec flag (when
available) only prevents inheritance across exec() calls, not fork().

gh-142927: Clarify pstats file output in docs and CLI ( #143388 )
...
When running the `profiling.sampling` module in pstats mode, the output
can be emitted in two different ways: text to stdout or a binary file
when the `--output` argument is set.
The current documentation and help text is confusing as it does not
distinguish between these two output formats so it may be surprising to
the user to get different formats depending whether `--output` is set or not.

gh-138122: Skip threads on EPERM in blocking mode profiler (GH-143368)
...
When using blocking mode in the remote debugging profiler, ptrace calls
to seize threads can fail with EPERM if the thread has exited between
listing and attaching, is in a special kernel state, or is already being
traced. Previously this raised a RuntimeError that was caught by the
Python sampling loop,and retried indefinitely since EPERM is
a persistent condition that will not resolve on its own.
Treat EPERM the same as ESRCH by returning 1 (skip this thread) instead
of -1 (fatal error). This allows profiling to continue with the threads
that can be traced rather than entering an endless retry loop printing
the same error message repeatedly.
