If other processes run in parallel, it would be possible to take time over 10s (timeout). I confirmed same `IOError: stream closed` was raised on my local box by setting shorter timeout. The reason of `IOError: stream closed` would be that the pipe is closed at ensure block in EnvUtil#invoke_ruby while a thread which reads from the pipe is alive. If killing threads before closing pipe, Timeout::Error is shown. It would be nice to know the cause of error easily if Timeout::Error was showen in the case of timeout. And more longer timeout would be helpful not to fail this test for Windows. I attached a patch. This increases timeout to 15s. Luis Lavena also confirmed this patch helped when tested manually on the worker machine. =end -- http://bugs.ruby-lang.org/
