It seems that I can use IO.select inside a ractor, but not call IO.wait_writable, which seems odd.

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)
