If this is not an option, you can also just move to Data::Dumper. It
gives up about 30-50% more CPU in session creation, but otherwise
shouldn't be too much of a drag.

Using it can be as easy as removing the _session_storable file in your
interchange root -- and removing all your old session files, of course.
