My impression is that 'fork' is difficult to implement portably.  You
could try, I suppose.  Or there's "run a separate Emacs and communicate
over pipes":

There are some aspects of sharing that may be hard (file descriptors).
Also setting up initial state of the worker process is hard if one
cannot truly fork.

I do wonder why there hasn't been more experimentation with this
approach, though, given that it is doable today just by running emacs as
a subprocess.
