Roberto,
Thank you for your feedback and assistance, it is very appreciated!
I did not consider the need to anchor my table, so thank you for alerting me to that necessity! :)
As I am returning the table via 'ra' I am just anchoring it there upon creating the first table. Am I correct in assuming that once this table is anchored in the stack that any tables added to it are also safe from emergency garbage collection?
