Couldn't figure out how to get around the IO blockages as per the talk page so any help would be appreciated, thanks in advance.

# Ruby has no direct access to mkfifo(2). We use a shell script.

end

Example run:

exec sh -c {test -p in || mkfifo in || exit 1;test -p out || exec mkfifo out}

 

 

# Run the event loop until done
