Issue #17659 has been reported by chucke (Tiago Cardoso).

Bug #17659: Ractor: can't call io/wait methods
https://bugs.ruby-lang.org/issues/17659

* Author: chucke (Tiago Cardoso)
* Status: Open
* Priority: Normal
* ruby -v: 3.0.0
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
It seems that I can use IO.select inside a ractor, but not call IO.wait_writable, which seems odd.

```ruby
require "io/wait"
ractors = []
1.times do
  ractors << Ractor.new do
    $stdout.wait_writable(2) # this fails
    # but this works
    # IO.select(nil, [$stdout], nil, 2)
    $stdout.puts "wow"
  end
end
ractors.map(&:take)
```
