cache_mem only defines the hot object memory store. Squid will use
significantly more than that. If your goal is to reduce memory usage,
then the idea is to _reduce_ cache directory size, not increase it.
Squid currently uses an in-core swap.state that keeps up with what files
are in the object store on disk...the more space you allocate to Squid
on disk, the more memory it will take to hole that swap.state.

So use a very small cache_dir setting (200-400MB, maybe?), and also set
cache_mem to 2-4MB. That should cause your Squid process to be somewhat
smaller.
