Subject: [ruby-core:101273] [Ruby master Bug#17366] Ractor odd issue with timeout + receive + sleep + take

Issue #17366 has been updated by ko1 (Koichi Sasada).


I can confirm with it:

```ruby
r = Ractor.new {
  begin
    pth = Thread.current
    Thread.new{ pth.kill }.join
  rescue => e
    p e
  end
}

p r.take
```

Bug #17366: Ractor odd issue with timeout + receive + sleep + take

* Author: marcandre (Marc-Andre Lafortune)

* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
I believe the following behavior is incorrect:

```
ruby -r timeout -e 'r = Ractor.new { Timeout.timeout(0.1) { sleep(1)       } rescue :timeout };             p r.take'
# => :timeout (ok)

ruby -r timeout -e 'r = Ractor.new { Timeout.timeout(0.1) { sleep(1)       } rescue :timeout }; sleep(0.2); p r.take'
# => :timeout (ok)

ruby -r timeout -e 'r = Ractor.new { Timeout.timeout(0.1) { Ractor.receive } rescue :timeout };             p r.take'
# => :timeout (ok)

ruby -r timeout -e 'r = Ractor.new { Timeout.timeout(0.1) { Ractor.receive } rescue :timeout }; sleep(0.2); p r.take'
<internal:ractor>:130:in `take': The outgoing-port is already closed (Ractor::ClosedError) # => not ok
```
