I reset Safari on OSX frequently, and do the same with Chrome. On iOS I run Safari in private browsing mode all the time. Not really to auto-delete cookies (it does that), but because if you have a history of websites and you start typing in the address bar, it attempts to auto-complete the URIs, which freezes Safari for a second, and delays keyboard inputting. Apple doesn't have a time-delay of 1-2 seconds after the previous keystroke, so its auto-complete is really annoying and slows down/breaks the UI. Bookmarks have to be empty too to work. That said, private-mode iOS Safari crashes a whole lot more than non-private mode. This usually happens on newspaper websites (UI hell) when all of the ad network and javascript widget garbage attempt to load. If you hit Stop-Loading after the article text is loaded, but before that other crap does, it fixes the problem. Funny, but disabling Javascript seems to crash more than leaving it on, but on different websites, likely for different reasons.
