Oui, there was an article a while back about a university making OOP optional for CS majors because of it.

Think of a library.
With the lock model, there is no librarian, so to keep order within the library, and to prevent people from fighting over the same book, a gate is installed to let one person in at a time.
With the transactional model the gate is removed and a librarian is added. If 2 people want the same book then the librarian kicks one of them out and alerts him when the book is returned.

What if they don't have library cards? Does she kick them both out regardless?

Sounds Awesome! Def going to make my job and life a lot easier. Thanks Intel

One a side note..
OOP is a very powerful and helpful feature, no sense in not teaching it.

Not sure if this is rhetorical, but in about a year hopefully. Haswell should be the next 'tock' (change in architecture) and will follow Ivy's tick (die shrink). Intel aims for one a year, so sometime in 2013. Wikipedia claims Q1, http://en.wikipedia.org/wiki/Intel_Tick_Tock , but there's no source for that part.

Overall good news. Unless Haswell/Broadwell has something mind blowing though, I probably end up skipping them and jump to Skymount or Steamroller.
