I split up this patch into two separate patches: one for SLRU and one for
the executor probes. I've done some documentation on the SLRU part, maybe
you can look over it (to make sure i didn't break anything).

I left the executor probes out of the documentation for now, since it seems
not to be clear how they would manifest.

Out of curiosity: Why do we want to pass the SlruCtl pointer down to the
probes? I don't understand what those probes are going to do with those
pointers, can you explain?
