Yes, that's why I called it hacky and dirty :) I keep thinking about
this, so I will probably fix it in a nicer way.

The problem is switching relative paths relies on the old $CWD if I'm
not mistaken and we need getcwd() for this. I'd love to have one
callback that says "$CWD has been switched from this path to that
path, do whatever you need to" that can be called any time, before or
after chdir(). I'll look more into it.
