Low-Lock Singletons In D

[dsimcha]

On the advice of Walter and Andrei, I've written a blog article 
about the low-lock Singleton pattern in D.  This is a previously 
obscure pattern that uses thread-local storage to make Singletons 
both thread-safe and efficient and was independently invented by 
at least me and Alexander Terekhov, an IBM researcher.  However, 
D's first-class treatment of thread-local storage means the time 
has come to move it out of obscurity and possibly make it the 
standard way to do Singletons.
