  Log:
  Handle MSG_NOSIGNAL flag in linux_send() by setting SO_NOSIGPIPE on socket
  for the duration of the send() call. Such approach may be less than ideal
  in threading environment, when several threads share the same socket and it
  might happen that several of them are calling linux_send() at the same time
  with and without SO_NOSIGPIPE set.
  
  However, such race condition is very unlikely in practice, therefore this
  change provides practical improvement compared to the previous behaviour.
