I have encountered that need in Boost.Pool, but only because of how
restrictive the Standard Allocator requirements are.  If it wasn't for them,
I wouldn't need one.

Like you, I'm more inclined to just declare global resources as normal
objects, and just create instances of them in main().  I have never used an
actual Singleton except as mentioned above.

So, maybe we don't need one after all?
