I generally consider "large" to be in the thousands, and you dont have
anything that high. I do see a large number of restricted python transform=
going on (from your HTML page you sent me directly) and I'm curious as to
why that number is about 700 -- that seems a little high to me, and may be =
leak source. During normal operation it is possible to see tens of
thousands of objects in use (particularly BTree items).
Tracking down refcount leaks in python can be a bear sometimes!
