Although the tests are rather synthetic, these results indicate ts-promise is pretty fast.
Note that e.g. 200 ops/sec actually means 2 million promises being resolved per second. Higher is better.

Notes:
- RSVP was excluded from this test because it doesn't support long traces.
- Bluebird complained about being rejected with a non-Error, which seems a false positive.
