Squid's great at keeping small objects in memory, but not large objects.
Its been a known problem for a while. I've got a dotpoint to fix it in
Squid-2.X; 3.x has a different memory object cache organisation which
will need to be revisited once I've got some more experience with memory
caching in 2.x.
