this DDD all recursive emulations immediately stop.
The simulations would have halted if *only* the outermost HHH was
pure and did not abort.

*That* is what
what Sipser's twisted-by-you words meant, not simulating a different
DDD that calls a pure simulator. The code of DDD, including HHH, is
fixed and "describes" a partial simulator; you can't in a program
magically refer to "itself", you have to arrange for the explicit
mention to fall together with its name (except in Lisp maybe).
