I'm not sure Brett's plan is such a great idea. If you look at the file
attributes in my demo above, they include a leading path element (based on
the executable location), so it *is* possible to use the pkgutil data
access APIs sensibly from a frozen module (and even when there's no path
component, I believe the recommended way of invoking pkgutil would fall
back to the current directory).

So I don't think we should decide what to do without first comparing the
behaviour of frozen pkgutil.get_data dependent code between 3.3 and 3.4.
