fix random EBADF problemHEADmaster
```ruby r, w = IO.pipe r.close IO.for_fd(w.fileno).close ``` This code closes a file descriptor `w.fileno`, but `w` doesn't know the closing. Another code can open same file descriptor with opening file (`f`). After that, the `w` will GCed and `w.fileno` is closed again, and `f.fileno` is closed too, so IO operations for `f` (`f.close`) will cause EBADF. To fix this issue, do this test in another process.
