I thought this would be of interest to the Haskell community: http://www.acmqueue.com/modules.php?name=Content&pa=showpage&pid=330 "The ever-growing popularity of small multiprocessors is exposing more programmers to parallel hardware. More tools to spot correctness and performance problems are becoming available (e.g., thread checkers8 and performance debuggers9). Also, a few expert programmers can write efficient threaded code that is in turn leveraged by many others. Fast-locking and thread-efficient memory allocation libraries are good examples of programming work that is highly leveraged." Viva le STM! -- http://wagerlabs.com/
