Can you try the below patch? I've ran into this by accident but haven't
gotten around to file a PR yet. I'm also not sure if this is relevant
to you problem, but it sure is a wait-for-something mechanism that
couldn't possibly work because it had its pipe ends switched so far.
(from pipe(2): The first descriptor connects to the read end of the pipe,
and the second connects to the write end)
