My program is a genetic algorithm based program, so I thought I just 
need to save a generation object of the population and reload it later 
then my program could continue. But after I saved a generation object 
from within python using cPickle and reload it from another program, it 
said that some class object couldn't be found. Now I realized that a 
program cannot be suspended and reloaded by just simply dumping and 
loading using cPickle/Pickle.

I will try stackless python later.

Thanks a lot .
