The UTM gets this from x86utm.
The slaves use the already allocated memory.
But they don't get to use the same memory that the simulator simulating them is using, as that leaks information that they don't get to know.
The information flow is only upward.
They have a memory buffer (as far as they see) that starts empty, and they put data in it, and they take data out, and only what they put in is ever there,
This is what is intended, and how it actually works.

They write to what they consider to be their tape, and the UTM figures out how to store that on its tape to be able to give it back when requested.

That is already what it does.
But if the simulated machine can see that there is a layer outside them, then it isn't correct.
It need not see this and my algorithm still works.

It has its own stack registers and RAM.

Then what does the "global" comment mean, every simulator should think it is the globally top level simulator, and be simulating the simulator
That was so that humans could see the level in an
output message. I don't use that anymore. It is disabled.
of the next level down (not doing that simulators simulation), so no simulator has "levels" in it for its own simulation.
From the master UTM's perspective there is one more level
before it sees the infinite recursion behavior pattern.
