Well, I think there are systems where pipe gives you a bidirectional
pipe, but where shutdown on the pipe gives you the ENOTSOCK error. I
think I've read that pipes on the GNU system are always bidirectional,
and if so, does shutdown work on them?

And I'm also curious about pty:s, I find it a rather annoying bug in
U*IX that there's appearantly no reliable way to make the process
reading the slave side of the pty get EOF. The standard (e.g. what
emacs does) way seems to be to write ^D to the master side, and just
hope that the tty is in canonical mode and that ^D really is the EOF
