Thanks, Peter. It never even occurred to me to look at the source code
around the call. I saw open() and thought "built-in open". I forgot that
the io package supplanted a bunch of lower level i/o.

I'll poke around a little and maybe open a bug report if I can't find any
explanation for the change in behavior.
