What does it mean when a sentence ends with しなくもない?

I think I get the general meaning, which is "This seems to have a deep
meaning." But I'm fuzzy on the implications of `しなくもない`.

Is it a contraction of `かも知{し}れない`? Something else?




This is a double negation. It is a way of saying "する" with less certainty.
