 - save/restore of the CPU state is not implemented (see machine.c).
-- Improve cpu state handling:
-  Step 1) Collect all the TC state in a single struct, so we need only
-          a single global pointer per TC.
-  Step 2) Use only a single TC context as working context, and copy the
-          contexts on TC switch. Likewise for FPU contexts.
