Why use the multithreaded one? Why not just use the process one? When I have 
done some tests the multithreaded one was not any better then the multi 
process one on a linux box but I have not tested it on other operating 
systems. Also the multiprocess  one is more reliable in that it is more 
resistant to memory leaks, bugs that cause things to crash etc. In my mind 
multiple processes is how you scale to multiple cpus in the most reliable way 
currently. Zope does it that way also. You use zeo an then run one zope 
instance for each cpu you want it to use. It scales nicely.
