I had a penalized site come back for just under two weeks beginning the 8/9th of February (as described in this thread [webmasterworld.com]).
I had originally thought that my efforts to clean up the site had made the difference, but now I'm suspicious again.
Did something happen around that time, like some kind of rollback, that would better explain the penalty being lifted temporarily? I remember reading that about Caffeine results disappearing for a bit during that time.
