There's no official singleton in the boost lib (yet). AFAIK it's simply
because failure to reach an agreement on what is the "proper" singleton
impl.
But you can always check the yahoo file-area, should be a couple of informal
singleton proposals there.

Otherwise I would recommend you to look at the policy-based singletons part
of Loki (see 'Modern C++ Design' by Alexandrescu) for a high quality
implementation. Especially if you want a thorough discussion of all the
subtleties involved.
