Right, so that basically fits in with option #2.  Option #1 has raised
various concerns since it was first proposed, including concern over the
possible expensiveness of dup() on some OS'es.  I just thought I'd
document all of the reasonable suggestions for completeness-sake, though
at this point I personally prefer one of the latter two options.
