curr_items vs total_items

[mark]

Hi
i get stats from my memcached version like this. I use cmemcached the python
api. What is the difference between curr_items and total_items.
Is there anyway I can make the memcached not remove any item from the
cache? I can give it how much ever memory it wants.
thanks
mark
