The C++ standard requires static destructors and atexit functions to
be executed in the opposite order that the corresponding constructors
were invoked and the atexit functions were registered. Since atexit()
may be called from static constructors, there should theoretically be
a single stack for destructors and atexit functions. But if that's not
practical, invoking the atexit stuff first is a fairly decent
approximation.
