No. A tutorial on memory consistency models would be too long to insert

Sutter's Mill is a good starting point even though it's C++ biased.
Two recent insightful talks on C++11 memory model with down and dirty
details:

I finally got around to watching this. Absolutely mind-blowing, and a
very very good talk. This is what I would point people at, although it is
a bit long (and necessarily so). Didn't seem like it took 3 hours :)
I take back all my arguments regarding the previous discussion, they were
all wrong, along with my concept of the "issues" with out-of-order
reads/writes. I really like how Herb explains that it doesn't really
matter where the re-ordering happens, to the coder, it's all the same (as
if the source code is reordered), and how you can't ever really reason
about code if it has races.
Is D prepared to do (or does it do?) the same things that C/C++11 does
with atomics? It seems it is a necessity. The docs on core.atomic are,
well, actually missing: http://dlang.org/phobos/core_atomic.html
