I've heard about this one, thanks for bringing it up. This probably isn't the right forum to be debating how to do thread safe code so I won't bang on about it, but the web page does note that double-checked locking works for 32-bit primitives -- I'm not sure if the boolean used in the previous discussion counts as a 32-bit primitive (I hope so, since int and float do).
