Hi,

Stefan Matthias Aust 
> as all primitives are written in Squeak

While this is true for most primitives it's not true for the "operating
system" support "interface" files and primitives that are currently written
in C.

Also the Squeak threads are not true pre-emptive threads (if I'm not
mistaken that is)... Will they be pre-emptive in the new jitter?

All the best,
