0. Record and save a large timeline (I'm using 96M, which was obtained by less than 2 minutes of compose-discard in gmail)
1. Close and open inspector
2. Load timeline recorded at step 0
3. Assure "Live native memory chart" experiment is enabled
4. Open inspector on inspector
5. Take a heap snapshot of the inspector with large timeline loaded
6. Compare snapshot size to JS heap size. I'm getting 132M for the former and 162 for the latter.
