Steps to reproduce the problem:
1. Open enough tabs to trigger the "Not enough memory to open this page"
2. 
3. 

What is the expected behavior?
Automatically trigger a tab discard to free up enough memory to open the page

What went wrong?
Tab discarding - a wonderful feature - isn't actually being used when chrome is using too much memory!

Did this work before? No

Tab discarding is a very cool feature. The most obvious use case though - when there are too many tabs open to continue using the browser - should trigger an urgent discard to free up enough memory to open the current page seamlessly. That'd be beautiful.
