I am confident that with longer compiled blocks and faster memory
accesses (direct addressing), the JIT compiler will generate really
faster code.

Another point would be not to systematically compile the block that was
just executed.

Yes, that is why I wondered about finer detection of cache flushes in
order to flush only the parts that need to. Actually, when say CINVP
occurs, all the cache is flushed...
