Ah, so it does.  It's too much hair to distinguish "child exited with
problem" from "could not close pipe and/or recover child info and/or
whatever other mechanics went wrong".  So I just punted.

And as I pointed out earlier, different awks do different things
anyway, so there's no reliable portable way to deal with the
status from close().
