Read the documentation on "cache_mem" please. "cache_mem" does not specify
the total memory requirement. "cache_mem" stands for the amount of RAM
reserved for intransit and "hot" objects only.

There is only one way, I guess: Limit your cache swap size. Release notes
have a description on how to calculate Squid memory requirement given swap

1GB swap / 10K avg_obj_size = 100K objects
100K objects * 100 bytes_per_hash_entry = 10MB RAM

Thus, the hash table will cost you about 10MB of RAM. Other stuff will
probably consume about 10MB more. Plus 8 MB for cache_mem. Thus, the total
would be around 30-35MB. I am not sure why it grows to 200MB.
