Subject: [ruby-core:100764] [Ruby master Bug#17310] Closed ractors should die

Issue #17310 has been updated by marcandre (Marc-Andre Lafortune).


Option 1 seems easy.

I don't have enough experience to know if `Ractor#close_outgoing` could be useful or not. I am assuming there will be a `Ractor#kill`, right?

* Author: marcandre (Marc-Andre Lafortune)

* ruby -v: ruby 3.0.0dev (2020-11-07T21:47:45Z master 2f12af42f7) [x86_64-darwin18]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
While backporting Ractors, I found this issue:

```ruby
10.times { Ractor.new { sleep(0.1) } }
sleep(1)
puts Ractor.count # => 1, ok
# but:
10.times { Ractor.new { sleep(0.1) }.close }
sleep(1)
Ractor.count # => 11, should be 1
```
