Squid using almost twice as much memory as was accounted for

Is this expected?

...Additionally, most operating systems do not allow processes to shrink
in size. When a process gives up memory by calling /free/, the total
process size does not shrink. So the process size really represents the
maximum size your Squid process has reached.
FreeBSD 6.2-RELEASE-p8
Squid 2.6.16 using kqueue, aufs.
Some squid.conf lines:
cache_mem 300 MB
cache_replacement_policy heap LFUDA
cache_dir aufs /cache 50000 128 256
cache_dir aufs /cache2 50000 128 256

http://wiki.squid-cache.org/SquidFaq/SquidMemory#head-09818ad4cb8a1dfea1f51688c41bdf4b79a69991:
...As a rule of thumb on Squid uses approximately 10 MB of RAM per GB of
the total of all cache_dirs (more on 64 bit servers such as Alpha), plus
your cache_mem setting and about an additional 10-20MB.
300 + (50 * 10) + (50 * 10) + 20 = 1320. That about covers it.
Other options have been kept default more or less.
