I am not a ZODB-expert, but I did some benchmarks with it. If you don't 
commit your transaction all changes will be held
in memory. This means you have to commit your transaction or at least 
make a commit(1) (subtransaction) from time to time.

Hope that helps,

I would like to hear of your experiences if you try the different cache 
implementation Chris Withers talked about.
