This is probably the ticket you were thinking of, it has discussion on
relevant topics:

Move show_message() into WP_Error class and add support for various WP_Error
features that are missing <http://core.trac.wordpress.org/ticket/12254>
It doesn't directly solve the admin_notices issue, but support for that use
case is obvious once the show_message() situation is worked out. A WP_Error
based messaging system could be used by plugins in admin_notices to avoid
display inconsistency even if they weren't using a more global error
registration API.

I imagine transients would be the best way to implement a system for adding
a message at any time and having it shown on the next pageload in
admin_notices, though you would probably want to also use _POST to make sure
it's the same user who caused the message to be shown.
