Tyler and I have been working on a white paper about threading for a long time now, figured I should try out the blog's new "attachments" feature and share a draft of it with you so you don't need to wait for the next CTP. 

One major caveat -- the sample code is ancient and won't work in current builds.  The threading APIs haven't changed for more than a year, but other random bits of code we used to build complete samples have changed -- we'll get that fixed for the final version of the paper.
