static void	onDeadReference ()
static void	scheduleDelete (DelFunc kill_the_singleton)

template<class S>

static void lumiera::singleton::AutoDestroy< S >::scheduleDelete

)

[inline, static]

Because this Policy class can be shared between several Singletons, we need to memoize all registered deleter functions for calling them at shutdown.
