But is text rendering "inherently leaky"? Or more leaky than large scale accounting data or etc?

At that rate, it seems like just about any messy, multilevel problem can be taken as inherently leaky and not something design paradigms can make easier. Maybe the solution is, "there is no solution" but as an optimist, it's hard for me to accept that.

(And yeah, I should have said "design paradigm", not programming paradigm).
