STM and locks have some interesting clean-up and (as is cited in the article) you really need for it not to crash and not to deadlock or go all priority-inverted on you.
Message-passing, on the other hand, doesn't need particular locking and crashes are (somewhat) simpler to deal with.
(And most any scheme I've encountered can deadlock, and will usually choose the most inopportune moment to demonstrate this capability.)

There's an older blog post here http://enfranchisedmind.com/blog/posts/thoughts-on-paralleli... that's worth a read.
