Ask HN: How does Safari on iOS manage memory for multiple tabs?

[pandatigox]

I'm dipping my toes in app development and I was curious how tabbed applications like Safari/alternative web browsers manage memory for multiple tabs. I guess Im more interested in how Chrome or Firefox on iOS would do it, since they probably won't have special privileges like Safari.

Chrome and Firefox on iOS are just skinned safari with their own sync and features. Apple does not allow third party browser engines and you absolutely have to use the one built into the system (webkit).
