If you call exit! in your at_exit block it will exit immediately and
prevent other at_exit blocks from running. That might prevent the default
message from being printed. You might also be able to wrap the rest of the
code in a begin; rescue SystemExit; end block instead. You may find this (

article helpful, especially the comment mentioned at the end.
