Why would block lag happen in singleplayer? It's not like you need an internet connection to connect to that, right? And if Minecraft can't keep track of all the entities, why does it cause block lag rather than FPS lag (simply isn't possible for something to slip past the for loops).
I don't know the technical explanation, but there's some sort of "Memory leak" in mob AI that causes most entities to put a heavy load on servers, even singleplayer ones. This bug was fixed in the latest snapshot for Minecraft 1.9.3. Once that's out we should be fine.
In the meantine, try turning your render distance below 8. This should help a bit by exploiting a mob spawning bug which causes fewer mobs to spawn and therefore fewer to be loaded.

Servers in singleplayer... really? There's this type where you don't need an internet connection?
EDIT: apparently, in singleplayer, Minecraft sets up a local server or something on your computer, so that singleplayer and multiplayer share some of the same code.

The signature is a lost art.
