Likewise, IO.copy_stream also fails to detect cross-thread
IO#close because it does not use waiting_fd infrastructure
in rb_thread_io_blocking_region.

r, w = IO.pipe
th = do
    IO.copy_stream(r, '/dev/null')
  rescue => e
    warn [ e.class, e.message ].inspect
sleep 0.1

Should I change IO.copy_stream and to avoid
stuck threads in these cases?
