Use send() in client library to avoid SIGPIPE
The client library lives in applications that may not be blocking or ignoring
SIGPIPE. Using write() can cause SIGPIPE to be raised in the application if the
proxy is restarted. If the application does not catch the signal then it is
terminated.
Make sure this does not happen by using send() with the MSG_NOSIGNAL flag.
