[devel] [PATCH hasher-priv v3 2/7] sockets: xsendmsg: get rid of SIGPIPE on socket writes

[Arseny Maslennikov]

In the daemon, we do not want to receive SIGPIPE and very much prefer to
handle emerging communication errors ourselves.

In the client, SIGPIPE is a bit more bearable. It prevents logging to
stderr, though, so we'd like to avoid that as well.
