Squid squid.conf comment is now rewritten to read

cache_mem

        NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
        IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
        USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
        THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.

        'cache_mem' specifies the ideal amount of memory to be used
        for:
                * In-Transit objects
                * Hot Objects
                * Negative-Cached objects

         [...]

Joe: What is your current rule-of-thumb on how to size the memory of a
Squid system? You have more experience than me on this, and I'd like to
add a note to the FAQ on this in addition to the existing extensive
discussion on why it uses all this amount of memory..

Henrik
