       I really do not like to ignore signals

   I hear you, but SIGPIPE is documented in this case, and we
   definitely don't want to just crash with it, and we're doing the
   right thing (disconnecting) if we see it.

You convinced me, I'll commit this in a couple of days (better to have
the code where the bug occurs instead of just special casing
setpeer()), could you test it once just to see that it works?
