  o Major bugfix
    - Possibility of an infinite loop if the returned value of the read/recv
      was 0. A returned value of 0 means that we've reached the EOF thus the
      pipe/sock is drained so return success not an error.
Fix possible infinite loop on pipe/sock_drain() If the returned value of read/recv is 0 (meaning EOF), we'll end up in an infinite loop (active wait) until something is written on the pipe which is not really what we want here especially because those functions are called from the main thread.
