I'm glad you figured out the problem, but I want to note that you
almost certainly want to be using os.PIpe rather than io.Pipe.
io.Pipe i
Yes, I am using io.Pipe, and passing in the PipeWriter side of it as Stdout
and Stderr on Cmd.
I figured out the problem, though. The executable which I am launching is
doing a write on a non-existent file descriptor upon shutdown, which
generates a SIGPIPE, per strace:
write(75,

Hi All,
I'm hitting a problem using os.exec Cmd.Start to run a process.
I'm setting Cmd.Stdio and Cmd.Stderr to the same instance of an io.Pipe,
and spawn a Goroutine to consume the pipe reader until I reach EOF. I then
