good idea, let's leave a todo.

the reason i don't like white-box testing is that you end up writing a lot of 
test harness code, which can have bugs, and you might end up  testing paths 
that aren't taken during actual query execution.

the planner tests typically take something like 40s to run, a few seconds on 
top won't make a difference. also, it's good to have everything in one place, 
so i don't need to remember to run two planner tests when making planner 
changes.
