Comment:

 Wow. This is just an awesomely bad regression. Thanks for testing. I'm
 still not sure how this data is persisting. According to about:cache, "New
 Identity" is properly clearing all cache entries..

 In fact, if I wait a minute or two, or do something else between samy.pl
 visits, it is in fact unable to regenerate my evercookies.. Sounds like
 the cache picked up some fun race conditions while we weren't looking...
