After 12 days of stalling, I told the bank to bugger off. They would not, could not give me an answer either way. At about the 10 day mark, the seller offered to carry the mortgage, and when I had his signature, I called the bank and cancelled.
I had heard of someone else locally that was in the same situation as I. The same bank approved his loan, and then backed out one day before closing. So, before telling them to bugger off, I asked if should be approved, would they be bound to make the loan if my situation did not change. They said no.
