I've been playing around with the idea for aome time now, but this
was absolutely the last straw :)

It's in the vault, folder singleton, there's also a testcase in
singletest.cpp. I haven't bothered about copyrights and documentation
yet (should be fairly obvious), that can wait until I get some comments
about the proposed interface. In short:

        class singleton is a public base class for singleton classes
        pro:	lets you create trees of singleton classes and register
                the correct class at runtime.
        con:	requires support functions in derived classes (sigh,
                no boilerplates in C++...)

There are still a few holes in the interface which I'm working on; but
for now, I'd appreciate any feedback to see if I'm on the right track.

Tested with g++ (egcs-1.1, latest snapshots) and MSVC++ (urgh, why can't they
support member templates).
