Seems like on restart Safari wants to revisit previously opened pages and crashes again ad infinitum. Isn't there a way to cold-restart iOS devices or some such (like the magic "Zap NVRAM and repair permissions" procedure back in PowerMac times)?
I've always found that behavior annoying. If I want to revisit the last page, I can find it in history.
I explained that there is a bookmark feature just for this sort of thing, but when you're used to doing something one way, change can be slow.
