Asked Google: "Clustering by compression".

"The crowd greedily reads confessions, memoirs, etc., because in its baseness it rejoices at the humiliation of the high, the weaknesses of the mighty. At the discovery of every vice it is in raptures: 'He is small like us, he is vile like us!' You lie, you scoundrels! He may be small and vile—but not like you—differently!"

In any case the quality that allows to quickly free all tied memory is not exclusive to a bump-type allocator; any allocator that exists on its own can do that. It is just that we do not often see standalone malloc-like allocators. But they are totally possible. A bump allocator supports other actions that are indeed exclusive to its design: partial free (set a mark and later "return" to it and free everything that was allocated after that mark) or allocating the last chunk step-by-step ("growing"). These are indeed unique to bump allocator, but the way it frees all memory is not.

For example, one might want to combine a bump and slab allocator: generally bump, but allow for 'free' for small sizes with subsequent reuse of the freed slab. This would be a tad slower than pure bump, but will have a better use of memory in certain scenarios.

Zen teacher talks with students, but then the students work on their own. They cannot get that knowledge in a dialogue. In Zen the situation is clearest, but it is same everywhere, e. g. in math.

"Arena" normally also implies the allocation algorithm is stack-like, but this is not a hard requirement tied to the implementation.

That said, here's an experiment conducted by some Soviet psychologist, I forgot the name. The man wanted to study intuition. So he invented an experiment that was supposed to trigger it in laboratory conditions. (Take a moment to marvel at that; how would you approach such a task?) He gave people a few puzzles. One was to place some sticks according to some rules. Yet another was to find a path in a maze. The secret was that the path in the maze was the same figure as the solution to the stick puzzle.

And he observed interesting results. People who solved the maze after the sticks found the path much faster than the control group. If a subject was asked to comment how he was solving the maze, at the start or halfway through, the speed dropped to typical. Subjects normally didn't notice the similarities.

So there is something to study here, although it is obviously a case of pattern matching, only subconscious. This is a jump of sorts, but not the one I mean. What I mean is a Zen jump.

There was a Soviet publisher Kniga (Book) that published only books about other books: book art, technology, bibliophile stories and so on. One of their books was a collection of short stories whose main topic was books, reading, writing or similar. One of stories was Bradbury's "Forever and the Earth", translated, of course, but very well. I was a teenager then an I remember being deeply impressed by it. I knew Bradbury, of course, but mostly from sci-fi and he wasn't really a sci-fi author. (One of Soviet sci-fi writers pointed out that Bradbury was pretty much anti-scientific in his stance.) That story made Bradbury stand out for me.

I've read that Malachi Martin described what he called "a perfect possession". I do not know where as I haven't found this piece myself. But the idea was that typical cases of demonic possession are imperfect, the victim is struggling, and the struggle is visible to the outsiders. A perfect possession does not manifest itself.
