Do you mind rebase your commits and squash them together, then force push to your branch so this pull request will be updated? I think it would be more useful to have just a single commit.

Ok. Here is the join commit tomas-stefano@7b27d85

Excuse my curiosity, but I wonder if my patch will be accepted ... or not :)

This also fails on 3-1-stable. So it will have to be cherry-picked on 3-1-stable and master.

This looks good enough to be applied if @tenderlove / @jonleighton agrees. I would later refactor it to use only destroy_associations callbacks, without the need to mix it with after_destroy callbacks.

Does the SQL work cross database?

I made some fixups to this patch, ported it to master and 3-1-stable, and then backported to 3-0-stable. Thanks for contributing.
