[illumos/solaris] set MSG_NOSIGNAL while writing to sockets Both these platforms have MSG_NOSIGNAL available, and we should set it for socket writes in the event that the SIGPIPE handler has been reset to SIG_DFL (i.e. terminate the process). I've verified via a quick program at https://github.com/sunshowers/msg-nosignal-test/ that even when the SIGPIPE handler is reset to SIG_DFL, writes to closed TCP sockets now error out with EPIPE. (Under ordinary circumstances UDP writes won't cause MSG_NOSIGNAL.) However, I couldn't find any existing tests which verified the MSG_NOSIGNAL behavior.
