Comment (by dgoulet):

 Results are here:
 https://people.torproject.org/~dgoulet/volatile/perf/0.4.0-ed0bc85ed0ac/
 (Only the `inuse` for now, skipping the `flamegraph`).

 Big takeaways:

 * The 10 min loop 10MB and 100MB file download through an '''Exit'''
 profile shows that we've reduced our memory usage by `~73%`.

 * The 10 min loop 10MB and 100MB file download through an '''Onion'''
 profile shows that we've reduced our memory usage by `~50%`.

 * The one time 100MB file over an '''Exit''' and '''Onion''' profile shows
 that we've reduced our memory usage by `~73%`.

 (0.3.5 results:
