Yep. That was my second guess. So what about the
dictionarys above the 2*class number?

Well, ignorance is a wonderful thing. It makes you
curious about stuff that if you knew what you were
doing might not be interesting.
I'm still wondering if the number of MethodContexts
hanging around at the beginning (of a fresh image) are
significant of something more. The difference in
number was curious.
I started this quest out of a curiosity to see what
squeak was made of (a megabyte here a megabyte there
and pretty soon your talking real memory). So it
became interesting to track anything with more than 1K
instances. And then I got curious to compare versions
to see if the numbers had changed dramatically or not.
The results seemed interesting enough to publish on
squeak-dev. I hope to get enough feedback to start
looking at more significantly interesting stuff next
