Question Involving the Dispatcher Lock

[blinksumgreen]

I know in Windows 7 they've done away with the dispatcher lock in favor of "several finer-grained synchronization techniques" via http://www.sevenforums.com/news/139...rformance-optimal-use-available-hardware.html

Can anyone explain what changes have actually been made in a little bit more detail?

I was wondering if I could get an explanation in a paragraph or so, or summed up in an article. I understood some of what they were talking about, but got lost in other parts.
