policyd-weight cache - how to disable?

[pl.zenon]

Hello,
I would like to disable policyd-weight cache because I have vps with low amount of memory and generally I don't need this funcionality. I tried to create a config file in /etc/policyd-weight.conf with all settings copied from defaults and modified $CACHESIZE string to value "0". Unfortunately after that any settings doesn't change... (Of course I restarted policyd-weight after configuration file creation)

Could you tell me how can I disable caching in policyd-weight?
