Title: Make sending anything wait until downstream component is ready

This is handy when you're doing something like:

```
'Initial' -> IN Merge(Merge) OUT -> PROCESS.IN SomeComponent()
```

where `SomeComponent` may not be ready and the initial is already sent to `Merge` knowing nothing about the downstream components.
