What's broken, exactly?  I don't see what's "old" or "broken" about
signal(3).  How is it being superseded?  

The standard says send() signals SIGPIPE on EPIPE, and (implicitly) that
signal() may be used to ignore SIGPIPE.  AIUI, that's expected to work
in all implementations.  Is it known not to work in Linux?  

I see the preprocessor conditionals in net.c, but it's not clear to me
what published behavior it's aimed at.
