Your parody is witty, and not without serious commentary;
You could try Jython.
Other than that, you probably want a threadpool, or perhaps to try

You'd probably better explain in English which things truly need to be
compared with what. Right now, your first version is, I believe, an O(n^4)
algorithm, which is extremely expensive, while your second (set-based)
version appears to be O(n^3), which is quite a bit better, but still not
stellar.
