It's still 5GB, which is a fairly large footprint, certainly for a
2-day session.

Can you describe in more detail how you edit email?  Which email
package(s) do you do, and what would composing email generally
involve?

Also, are there any background activities that routinely run in your
Emacs sessions?

That's for Carlos to say.

Thanks for the info.
