I don't know, I've had one tab cause other tabs to crash all the time, which is something that confused me considering the supposed isolation that should be happening.
edit: not sure why I've been dv, but I'd like to add that one thing I've noticed is that this will usually happen when I open links in a new tab, somehow all those tabs become linked and if one becomes unresponsive they all do. For those who claim I should stop opening links in new tabs, I say: welcome to 2004, this is the whole purpose of tabbed browsing. If you;d like to try to reproduce this: go to facebook and open the first ten links in your newsfeed in new tabs (either by middle clicking, ctrl+click, or context menu) I don't normally do more than one or two at a time but ten will force the issue. then go to another tab that isn't connect to those other 11 it'll work fine while those 11 will look like they're on pause.
Yes. Sandboxing makes sense when you think of browser as operating system. Isolate each process to increase security and crash-resistance. Makes sense, but it takes more memory.

Note: I haven't tested this in other browsers.
