I think they should all be side-effect free (as much as possible)
anyway. Someone might well want to run an individual test in an existing
Emacs session, without that session getting messed up.

I don't know. Running them all in one is the only way to get the final
number of tests run / passed / failed to be accurate. Running them in
separate Emacs's would allow them to run in parallel, which would be
faster, but might be confusing?
