Any thoughts on what uses_transaction wants as an argument? I can't
help but feel like I've tried 10 combinations of ways to do this, and
there's some 11th way that will be easy but I haven't thought to try.
For context, my code doesn't even use transactions; it's using a 2nd
DB connection to a slave DB, which will be different in some envs and
not others. This seems to get tripped up by transactions since the
master connection makes a change to the DB and the slave connection
needs to see it right away. (Yes I know in production there are
latency issues, that's acceptable in this case.)
