Hang in there Jimbo,
Pontius makes a very important point there about the review process. That is possibly why it is taking a while. Means that a couple of the interviewers did not agree on your performance, so obviously some of them think that you're capable and think you should be in. Hope that you do hear soon. If not, follow the advice of my learned friend pontius and give them a bell at the end of the week.
Best wishes.
Bunty
