Yes, everything works :-) Except the bytecode trace hook. The machine
code is really terrible at all points of view, but you can JIT whatever
piece of Python code you like - generators, nested scopes, class:
statement bodies, all these cases where Psyco give up. That's the point
of the approach, really :-)
We have a minor detail to solve before it can be tested on larger
examples, though - it exhausts the 32-bit address space far too early
(without actually consuming much of the reserved pages) and then we get
a MemoryError. It's a back-end problem; Arre started working on that
