py-psutil: update to 6.1.0.

6.1.0
=====

2024-10-17

**Enhancements**

- 2366_, [Windows]: drastically speedup `process_iter()`_. We now determine
  process unique identity by using process "fast" create time method. This
  will considerably speedup those apps which use `process_iter()`_ only once,
  e.g. to look for a process with a certain name.
- 2446_: use pytest instead of unittest.
- 2448_: add ``make install-sysdeps`` target to install the necessary system
  dependencies (python-dev, gcc, etc.) on all supported UNIX flavors.
- 2449_: add ``make install-pydeps-test`` and ``make install-pydeps-dev``
  targets. They can be used to install dependencies meant for running tests and
  for local development. They can also be installed via ``pip install .[test]``
  and ``pip install .[dev]``.
- 2456_: allow to run tests via ``python3 -m psutil.tests`` even if ``pytest``
  module is not installed. This is useful for production environments that
  don't have pytest installed, but still want to be able to test psutil
  installation.

**Bug fixes**

- 2427_: psutil (segfault) on import in the free-threaded (no GIL) version of
  Python 3.13.  (patch by Sam Gross)
- 2455_, [Linux]: ``IndexError`` may occur when reading /proc/pid/stat and
  field 40 (blkio_ticks) is missing.
- 2457_, [AIX]: significantly improve the speed of `Process.open_files()`_ for
  some edge cases.
- 2460_, [OpenBSD]: `Process.num_fds()`_ and `Process.open_files()`_ may fail
  with `NoSuchProcess`_ for PID 0. Instead, we now return "null" \ 
values (0 and
  [] respectively).
