  22     msg/simple/Pipe: avoid returning 0 on poll timeout
  23
  24     If poll times out it will return 0 (no data to read on socket).  In
  25     165e5abdbf6311974d4001e43982b83d06f9e0cc we changed tcp_read_wait from
  26     returning -1 to returning -errno, which means we return 0 instead of -1
  27     in this case.
  28
  29     This makes tcp_read() get into an infinite loop by repeatedly trying to
  30     read from the socket and getting EAGAIN.
  31
  32     Fix by explicitly checking for a 0 return from poll(2) and returning
  33     EAGAIN in that case.
