What you should really do is write a generator that would generate
models with a configurable number of entities, abstract entities,
mapped supper-classes, embeddables, relationships, fields, and so on.
You could integrate it into the build process to verify memory
consumption after every change in the Hibernate code. This would allow
you to find problems before you ship a new version of Hibernate.

It should be a good job for a student. :-)
