The memory cache and the disk cache are pretty seperate. squid can
remove a memory from being in the "memory cache" (ie, the whole object
is in memory) whilst still writing it to disk as it comes off the
network.

I don't believe anyone's done much work investigating Squid's behaviour
with small and large memory objects.
