They aren't very big, so it wouldn't hurt to have a lot of them. This would more generally cover the case also where someone backs up, then requests a new address and receives a big payment with it. Maybe there should be separate queues so one type of demand on addresses doesn't deplete it for the others.<br/><br/>The addresses would be created and stored in the normal place, but also listed on a separate list of created-but-never-used addresses. When an address is requested, the address at the front of the never-used queue is handed out, and a new address is created and added to the back.<br/><br/>There's some kind of rescan in the block loading code that was made to repair the case where someone copied their wallet.dat. I would need to check that the rescan handles the case of rediscovering received payments in blocks that were already received, but are forgotten because the wallet was restored.<br/></div></div> text/html
