Microsoft Research Showcases New Browser Prototype, "Gazelle"

Ars Technica reports that Microsoft has opened up about "Gazelle," a new browser prototype of theirs that is modeled after the underlying concepts of operating system design. "A research team led by Microsoft's Helen Wang recently published a report about an experimental browser prototype called 'Gazelle' that uses processes to isolate page content elements originating from different domains. It builds on the concept of multiprocess browsing but uses more fine-grained isolation to expand on the security advantages that are already delivered by existing multiprocess browsing models. But is it an operating system, Microsoft Research's analogue to Google's Chrome OS? Not quite."

Color me less excited :/

After reading that article, I'm much less excited than I was. I had assumed it was something similar to Google Chrome OS, but it's not even something that seems like it turned out very well for Microsoft, or something that can have yet undiscovered major issues on the horizon. The idea seems to have turned out overly complex to work around the limitations with the approach, and all that in a resource hungry .NET application. It says they're hopeful to get the per-tab RAM usage down from 16 MB, but I have to wonder by how much? This approach doesn't seem much better than running a process-separated browser written in Java. Ugh.

I have a hard time understanding the decision to use .NET, but perhaps it was a security decision? Anyway, it doesn't sound like the optimal choice, when the project all revolves around low-level features like isolating the tabs even further.
