Subject: [ruby-core:101204] [Ruby master Bug#17360] Objects disappear from ObjectSpace after using Ractor

Issue #17360 has been reported by Dan0042 (Daniel DeLorme).

----------------------------------------
Bug #17360: Objects disappear from ObjectSpace after using Ractor
https://bugs.ruby-lang.org/issues/17360

* Author: Dan0042 (Daniel DeLorme)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
Test:

```ruby
GC.disable
STR = -"testing 123"
x = STR.dup
puts "before:"
ObjectSpace.each_object(String){ |s| puts s.object_id if s == STR }
Ractor.new{ }.take
puts "after:"
ObjectSpace.each_object(String){ |s| puts s.object_id if s == STR }
```
Result:

```
before:
60
80
100
<internal:ractor>:38: warning: Ractor is experimental, and the behavior may change in future versions of Ruby! Also there are many implementation issues.
after:
80
```

Expected result:
Same object ids should be printed before and after

(BTW why 3 strings with the same value? shouldn't it be 2?)
