Nice work Cristian!

[cristianbote]

Based on recent findings I've included an update(1) in componentDidCatch in order to pickup on the changes. @developit I think now this is pretty safe for nested thrown promises, cause it does not read any children static property.

Is there any reason why this would lead to bad perf?

Let me know your thoughts.
