When I was doing a lot of DBIx::Class work, I contemplated writing a plugin to allow me to lock and and unlock automatic relation fetches and die (throw) if one was attempted when locked. I would carefully prefetch my queries (auto-fill relations from a larger joined query) and if something changed or there was an edge case I missed that caused fetching deep in a loop, it might kill performance, but be hard to track down if not given the best directions on what caused it other than "this is slow". It's one of those things that in the long run would have been much more time effective to write, but the debugging never quite took long enough each time to make me take the time.
