Those and Metal XTAL Ground pins, luckily in that case there are only 4 pins total, so they're easier to deal with, but they annoy me because its such a simple part.
Saving them for last is exactly the right thing to do, since you can then heat the joint while applying a small force to remove the pin from the hole. (Danger--too much force and you'll find a PC trace attached to the pin. ;-) If there are multiple such pins, you sometimes have to "walk" the part out by cycling through heating and lifting at each pin in sequence. Speed is critical--too fast and you risk lifting traces because the solder is not melted, too slow and you risk heat damage to component and traces. -michael New, faster SUDOKU v2.0 solver for Apple II's!
