i think that a different problem, which may exist in netbsd, but i haven't
checked.

The problem here, from my pov, is that either documentation or implementation
is wrong.  or, sockets and pipes do not behave the same, so the documentation
is lacking.  which is it?

solaris behaves differently.  solaris does not return HUP until the pipe is
drained.  freebsd and linux behave like netbsd.  the solaris behavior seems
more logical, but whatever.
