I've attached a simpler code (simpletest.py) that gets down to the problem here 
in my opinion. From what I have seen it is a problem with the JIT spending most 
of its time trying to optimize the code - not tracing, optimizing. Small changes 
can really help the JIT to figure it out.. like adding an extra letter that 
isn't d, e, or f to the string passed to execute() or changing one of the if
