There was a nice blog-post about implementing low-lock singletons in D, here:

One suggestion on Reddit was by dawgfoto (I think this is Martin
Nowak?), to use atomic primitives instead:
http://www.reddit.com/r/programming/comments/1droaa/lowlock_singletons_in_d_the_singleton_pattern/c9tmz07
I wanted to benchmark these different approaches. I was expecting
Martin's implementation to be the fastest one, but on my machine
(Athlon II X4 620 - 2.61GHz) the implementation in the blog post turns
out to be the fastest one.
And it was a big thing because of that. Also keep in mind that atomic
ops are _relatively_ cheap on x86 the stuff should get even better on
say ARM.
