People have experimented with making the ceval loop use direct
threading.  If I recall correctly, the resulting speedup was not
significant.  I suspect the reason is that most of Python's opcodes
do a significant amount of work.  There's probably more to be gained
by moving to a register based VM.  Also, I think direct threading is
hard to do portably.

If you are interested in JIT, take a look at Psyco.
