Personally, I don't feel Boost needs a singleton utility. Singletons
themselves aren't *really* ever required. (When have you *actually* required
you *cannot* make more than one?) If you don't need more than one, don't
make more than one. A singleton takes this idea and forces you to mutilate
your class to fulfill some silly requirement.

Perhaps some boost::global<T> utility would be better, but a singleton
itself is bad practice, in my opinion. boost::global<T> would merely create
a global access point to T:

typedef boost::global<int> global_Int;
global_int.get() = 5; // getting the global int

It could have policies, to get the advantages of a singleton without the
unnecessarily intrusive nature of a singleton. Lazy initialization,
thread-safety, etc.
