Updates to pull requests (especially comments) should display in real-time

I think all sorts of updates would be great to have in real-time, but the primary one is comments. Currently, when discussing a pull request with a fellow user on Bitbucket, you have to reload the page in order for their new comments to load. This is a pretty awful user experience, since there may be several comments generated in one discussion. If they make a new comment while you are typing, you'll miss out on new, possibly relevant information until you manually reload the page!

Real-time updates would also be much appreciated on the "view all PRs" page. For instance, if one of my pull requests was merged, I'll have to refresh the page page to see that that it got merged.

Of course, this is not an issue if you're coming to the page for a brief, one-time visit, but I often have the PR page open in the browser as I work, since we try to move quickly on those. It's tough to use it like a modern web app without real-time updates.
