[mod_python] connection pooling?

is it possible to do connection pooling of database handles in 
mod_python? my understanding is that for the common apache/linux mpm 
(prefork) this amounts to having lots of connections open to the db.. 
i'd like to have a global pool of connections for the server, is this 
possible?

somewhat related.. when apache is using the thread mpm, does mod_python 
use a single interpreter for all the threads, or does a different 
interpreter in each thread?

thanks,
