I have read alot about Software Transactional Memory, especially in relaiton to Haskell but I am trying to figure how it is different from database transactions? Are there some advantages I do not understand with STM?

In terms of actual low level atomic instructions and memory fences (I assume they're used), how do you implement STM? The part that's mysterious to me is that given some arbitrary chunk of code, you need a way to go back afterward and determine if the values used in each step were valid. How do you… >>> More
