I don't like the atexit call for registering the destructors,
Why? You can't rely on the presence of any globally contructed objects during atexit. So why should once_class object be different?
Also the MSVC compiler is doing just that for local static objects dtors: scheduling a call to atexit.
The MSVC compiler will schedule a call for each static object, so they are destroyed in the correct reverse order, and correctly interleaved with other calls to atexit, as per 3.6.3p3 of the C++ Standard. Having a single call that destroys all the objects means they are not interleaved as one might expect. One could have a call for each object that just destroyed the last object constructed, and destroyed the list once it was empty; that would be better.
