It seems like the NDELAY flag on a pipe fd on sys5 also says that the pipe
should be dismantled as soon as the writer process dies.  This means that
any data in the pipe when the writer process dies will be lost.  This makes
no sense to me, and is not an obviously documented side-effect of NDELAY.

So far I've discovered this empirically on IRIX (SysV derivative) and
surprisingly also Ultrix 3.1 (it seems).  SunOS uses BSD semantics.

What's the deal here?
