If you can suggest a way to split the contents of session_data into its
component elements, I can tell you.

Otherwise, I could send file containing the contents of one of these monster
huge sessions to someone after we tried to sanatize the data..

Not sure if I ever mentioned, but we're using the mysql session handler
