Not really: if the only reason not to have close_stdout ignore EPIPE is
a bug in a fringe shell on a mis-configured system, then:
- either you don't care, despite the "trouble to reproduce and
diagnose", and you make it fail silently
- or you work around it by unignoring SIGPIPE.
I'd prefer to have EPIPE ignored, so I can prepare a patch to most
coreutils for (2) if you wish.
