something along these lines would probably be great to have eventually
(even if we don't have the bandwidth to implement it quite now).
Would you care to open an issue with some of these thoughts and any
other info you can think on the design?

That would also be a place to have a discussion of how to tie a
session storage mechanism (even if it can't pickle/save everything)
with our new, more powerful history handling that uses sqlite.
