perhaps you still don't understand the root problem: "true preemptive
multithreading" requires a certain program architecture to take
advantage of it (including but not limited to: how the functions are
written, placement of data, access patterns to the data, external
interface requirements).  if emacs does not have this particular nature,
force-fitting it to make it so is a royal PITA.  if you don't force-fit
it, you will never get the true preemptive multithreading "experience".

   there is at least some speed improvement.  [...]

here's an analogy: rollerskates on two separate people and they both go
fast.  rollerskates on a potato-sack race pair and you get injuries and
lawsuits, coredumps and bug reports.  (and the pair still goes slow.)
