I am very sorry here... I too am sometimes short of time, so I have to blast 
some pseudo-code out in order to get my point across, rather than doing a 
quick write-up...

I promise you that once I get my atomic::once out of the pseudo-code stage, 
and transform it into a fully working prototype it will have 
documentation...

I removed the ctor from atomic::once, but I need to think about that some 
more here...

I am using an augmented type of reference counting for this. It will dtor 
the static object only during/after the dtor for atomic::once runs and when 
the count drops to (-1). I used to wait until it dropped to zero in the 
version with the ctor because I was using it to init to 1.
