"accounted memory" is memory that Squid knows where it is used and how
to count it. Unfortunately not every memory allocation in Squid is
accounted.

Another sources for the difference:
* Memory fragmentation
* Free heap. Most memory allocators maintain memory allocations inside
the process and never (or rarely) shrinks the process sice once it has
grown.
