Silkroad, thank you for that amazing post. This is truly horrendous. I just got the 5.1 update. To think they would have made it so much worse is truly hard to believe.
THIS IS THE BIGGEST SECURITY RISK IN THE HISTORY OF OSX! DO NOT USE SAFARI!
Apple has clearly given us all a big "F U" with this. No doubt Safari works in LION! Just pay $30 and you can browse the internet securely again. My guess is Apple is not going to do a thing about this unless Engadget and the other sites point out what a serious securtity issue this is, the worst ever for OSX.

Safari v5.1 (Build 6534.50) accepts all cookies no matter which Block Cookies choice I select. But the current list of cookies is *much* longer than before, and includes many new ones -- even though I haven't visited any new websites. That is, it's the cookies from before plus a bunch of new ones I've never seen until now, many with nonsensical names.
Then there's this new wrinkle: I visit site xxx.xxx and it writes cookies to my Mac. I then return to Home, go to Preferences, delete all cookies, and close out Safari. When I start Safari again and check cookies (mind you, I haven't done any navigation at this point, I am still at Home), many of the cookies I just deleted last session have reappeared -- deleting them doesn't make them go away. Some are from online banking websites like bankofamerica.com, and citi.com that I have visited during some previous session. Some are from other vendor-type websites that I didn't visit. Some are from mystery sites (with strange names that I dare not visit).
New wrinkle #2 is even better: as I'm deleting individual cookies, maybe a second or so later (while I'm still in Preferences, looking at the list of cookies), the cookie *I just deleted* reappears. I didn't visit that website this Safari session. I didn't visit it last session, either. In fact, maybe I've *never* visited that website. Yet its cookie is there, and when I delete it, it just pops back into the list of cookies. (No, it's not from Apple or Google or doubleclick or any other source you'd suspect.) I can delete it 10 times. Doesn't matter. It pops right back into the list at the same location as before. All 10 times.
The cookies that keep reappearing (no matter how many times I delete them) are not from websites that require me to log in, so that's not it. Some are from websites that I have previously visited, and some are mystery cookies.
It seems that some as-yet-undefined type of cookies are immortal.
As mentioned before, if I select Private Browsing, websites I'm currently logged into this session will no longer allow me in. And I can't log in to them, either, unless I turn off Private Browsing.
