Comment:

 The setup I tested on was stock. And I'm not able to reproduce those
 errors on anything but the old laptop that I was using over the holiday.

 Then I updated the XAMPP install on that laptop and the problem went away.
 It's likely specific to that version of PHP or MySQL. Here's the before &
 after phpinfo's showing what versions were runing:

 I've never seen a MySQL resource id less than 1, but you're right about
 is_resource(). New patch using that is coming. We may want to include it
 just in case there's a bug in a specific version of PHP or mysql_connect.
