Python is a programming language, where the programmers are
responsible for what the parallel programs they write do and how do
they cope with the various dangers of concurrency.  If the program
crashes, the programmer has only him/herself to blame.

By contrast, Emacs is a program that lets users process text in
various scenarios, where users expect Emacs to react gracefully to
errors.  Emacs the program has a very large global state that doesn't
work well with any concurrency, and which any programmer will keep as
far from as possible.  If Emacs crashes, users blame Emacs, not the
Lisp they wrote.

So there's a large difference, and therefore not every technique used
by a programming language can be used by Emacs to achieve similar
goals.
