Is the new D threading model emulating processes + shared memory?

[Leandro Lucarella]

I was thinking about the thread "Sharing in D" and it came up to my mind
that what it's been done with this model is just emulating processes +
shared memory. If you program you application with processes instead of
threads and shared memory instead of "D shared" type (or global variables
in general), you get what D is trying to do: clearly separated memory
areas for shared and unshared data, and protection.

So, what are the advantages of using threads+shared in D 2.0 compared with
processes+shared memory in D 1.0? I guess it's just simpler to program,
and maybe, more familiar to "threads programmers" (people that are not
very used to program using processes). Well, I guess you can have a little
faste context switches too, but I don't think this his a huge gain in
modern operating systems.
