 I get EBADF now:
 
 TestIO#test_readpartial_locktmp:
 Errno::EBADF: Bad file descriptor
     /home/ew/ruby/test/ruby/test_io.rb:2870:in `readpartial'
     /home/ew/ruby/test/ruby/test_io.rb:2870:in `block (2 levels) in test_readpartial_locktmp'
 
 Testing the following:
 
 --- a/test/ruby/test_io.rb
 +++ b/test/ruby/test_io.rb
 @@ -2874,6 +2874,7 @@ End
        assert_predicate(th, :alive?)
        w.write(data)
        Thread.pass while th.alive?
 +      th.join
      end
      assert_equal(data, buf, bug6099)
    rescue RuntimeError # can't modify string; temporarily locked
 
 I'm not sure if setting th->waiting_fd for rb_wait_for_single_fd
 is a good idea.  I think any poll/select wrappers should reload fileno
 from IO objects on EBADF, because th->waiting_fd does not scale.
