[ruby-core:120716] [Ruby master Bug#18613] Voluntary wanted: Some signal-related tests fail on FreeBSD 13

["hs (Hideki Sakamoto) via ruby-core" <ruby-core@ml.ruby-lang.org>]

Issue #18613 has been updated by hs (Hideki Sakamoto).

File patch-test_io_console_test__io__console.rb added
File patch-test_ruby_test__thread__queue.rb added
File patch-test_ruby_test__thread.rb added

I apologize if my comment on the closed ticket is inappropriate. By the way, these bugs seem to have been fixed in FreeBSD 13.4 (or 13.3).

I applied the attached patch to the Ruby 3.4.1 source and tried "make test-all" dozens of times in FreeBSD 13.4(while checking #21045), but the error no longer reappeared.

<pre>
% tar xf ruby-3.4.1.tar.xz
% cd ruby-3.4.1/
% patch < patch-test_io_console_test__io__console.rb
% patch < patch-test_ruby_test__thread.rb
% patch < patch-test_ruby_test__thread__queue.rb
% ./configure
% make
% make test-all
</pre>

While not a direct reference, a bug report similar to this bug has been reported in FreeBSD Bugzilla – [Bug 277429](https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277429)  and appears to have been fixed in 13.3.

Some tests fail randomly on FreeBSD 13.

```

All of the tests is related to signals. I guess something around signals has changed in FreeBSD 13, but I'm unsure. The failure occurs at high frequency in CI, but rarely does on my FreeBSD shell. We need to investigate what happens.

@knu is the platform maintainer for FreeBSD but he is busy. Contribution who is familiar with FreeBSD is welcome.

To make it easy to monitor the CI results, I tentatively skipped the three tests on FreeBSD https://github.com/ruby/ruby/commit/17e09f033c4d3b786672ba16d2c5d935482a2fad . If you investigate the issue on FreeBSD, please delete test/excludes/TestThread.rb and test/excludes/TestThreadQueue.rb, and remove the guard in test/io/console/test_io_console.rb.
