 // happen at a really bad time and under the loader lock. This facility is
 // mostly used by base::Singleton.

 // The usage is simple. Early in the main() or WinMain() scope create an
 // AtExitManager object on the stack:
 // int main(...) {
 //    base::AtExitManager exit_manager;
 //
 // }
 // When the exit_manager object goes out of scope, all the registered
 // callbacks and singleton destructors will be called.
