Stop the presses!  I noticed my POS mining performance fixes aren't in the testing_0.4.3 branch.  I know it's a hard change to test, because you have to have a big wallet with lots of ripe POS inputs to see if it really works. So far I'm getting fantastic results performance wise. But I need a few days of non-stop POS minting to be sure I didn't break anything.
