   each ASID change. Using the MMU modes to implement ASIDs hinges on
   implementing the global bit efficiently.
 - 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.
