Review Comment:
Although I haven’t implemented it yet, I’ve been considering that this
approach would lead to three different ways of handling exceptions in the
background thread:
1. ErrorEvent
2. Completed future
3. Exception
It feels a bit inconsistent, but I’ll try this out first. If it works, We
can revisit and refactor this issue later.
