## Discussion topics

### Tokio switch

- Pros

- Lots of existing frameworks depends on tokio;
- Cons
- Have some similar API with inconsistent behaviour;
- Yu-Wei will investigate;
- Not really a priority at the moment;

- Flume can block by pausing the thread or deferring to an async runtime;
- Passing all the tests;
- Still quite experimental;
- We could start using it;
