Re: [bug-inetutils] already connected when closed

    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.

Seems like the only alternative is the inferior-to-the-user choice of
invariably disconnecting ...

FWIW, SIG_IGN occurs in several other places, though I'm not sure if any
are exactly comparable:

cmds.c:172:  signal (SIGPIPE, SIG_IGN);
cmds.c:1534:  old1 = signal (SIGINT, SIG_IGN);
cmds.c:1535:  old2 = signal (SIGQUIT, SIG_IGN);
ftp.c:390:  if (abrtflag && oldintr != SIG_IGN)
ftp.c:507:      if (abrtflag && oldintr != cmdabort && oldintr != SIG_IGN)
ftp.c:594:      oldintp = signal (SIGPIPE, SIG_IGN);
ftp.c:697:  oldintp = signal (SIGPIPE, SIG_IGN);
ftp.c:925:      oldintp = signal (SIGPIPE, SIG_IGN);
ftp.c:1105:  signal (SIGINT, SIG_IGN);
ftp.c:1539:  signal (SIGINT, SIG_IGN);

Best,
