Only current revisions of objects are ever activated, so this is not a
good measure.  There is generally no correlation between Data.fs size
and memory consumption.  Also, the size of an object when serialized
(pickled in the Data.fs file) does not correlate to the size of the
object in memory in any straightforward way.  Lot's of objects like
database adapters cache run-time information like result rows,
connection objects, etc.  None of this information gets serialized.
