@tlhunter this PR could do with a better description. I'm not sure what process tags is and why it's added to the snapshot

[tlhunter]

Just rebased on the chai -> assert migration

[watson]

I would prefer a few minor things to be cleaned up, but since the holidays are coming up, I will not want to be a blocker, so I'll approve this PR (as it's just minor optimizations). It would be best to just fix them, and feel free to do so and to get someone else to approve the PR afterwards, but it could also be fixed in a follow-up PR if you prefer.

@watson @BridgeAR I'm doing a lot of work in this area right now so I'll address the nits in the PR I'm working on today.
