/**
 * This class is a creation policy for the utilspp::singleton_holder. The
 * policy is creating the singleton by a static memory. The constructor is
 * called the first time we call the utilspp::creation_static::create()
 * function.
 *
 * This creation policy is very usefull since it rely on static allocation.
 * It means that the creation is automatically thread-safe, since compilers
 * static ensures that static allocation is thread-safe.
 *
 * Note don't use this class with a lifetime policy that allows revivals. 
 * Be carefull with this policy since it won't respect the lifetime policy.
 * It will eventually be destroyed, but at the end of the program.
