That's good.

Uh, now I'm confused again. The way I envisage it, each imported
function would contain a plan. So each would have the one and only
reference to that plan. So, if there was a need to drop them, I would be
dropping the last reference to the plan.
Let me ask the question another way... is there any reason to drop plans
other than limiting memory usage?
I couldn't find anything in the docs to suggest there was but want to be
sure.
