You can dump heap whenever you want - you don't need to wait for out
of memory. If you're using a Sun VM then jmap or jvisualvm should do
the trick. You can then directly compare the workspace tree size
between the Eclipse instances.
If I get a chance today I'll try to have a go with a large workspace
I've got lying around.
