I've heard the freezer trick before, but I've never tried it. Is it likely to be a permanent fix?
No, it won't be a permanent fix. Once you've got the stem out, you will have to sand down a bit of the tenon. Use very fine sanding paper. Wrap it around the tenon, hold between your fingers and then rotate the stem. Try fitting the stem ever so often without using force. You don't want to take off to much. A tenon should not have a to tight a fit because once you start smoking, the heat will let the components expand.
