Altering the Database without Rolling Back Users

Kenneth Fisher wants to change a database:

If this strikes a bit too close to home for you then you need to look at the ROLLBACK clause. It’s great for killing and rolling back all of the current connections before making my change.

But this is a pretty sensitive app and if there’s something running I have to let it finish. No ROLLBACK allowed. But I’m also not going to wait forever to see if my alter is going to happen. Turns out there is a nice easy option for this too.
