-// space for T that supports a LinkerInitialized constructor. T must
-// have a default constructor, which is called by the first call to
-// get(). T's destructor is never called if the LinkerInitialized
-// constructor is called.
-//
-// Objects constructed with the default constructor are constructed and
-// destructed like any other object, and should never be allocated in
-// static storage.
-//
-// Objects constructed with the LinkerInitialized constructor should
-// always be in static storage. For such objects, calls to get() are always
-// valid, except from signal handlers.
-//
-// Note that this implementation relies on undefined language behavior that
-// are known to hold for the set of supported compilers. An analysis
-// follows.
-//
-// From the C++11 standard:
-//
-// [basic.life] says an object has non-trivial initialization if it is of
-// class type and it is initialized by a constructor other than a trivial
-// default constructor.  (the LinkerInitialized constructor is
-// non-trivial)
-//
-// [basic.life] says the lifetime of an object with a non-trivial
-// constructor begins when the call to the constructor is complete.
-//
-// [basic.life] says the lifetime of an object with non-trivial destructor
-// ends when the call to the destructor begins.
-//
-// [basic.life] p5 specifies undefined behavior when accessing non-static
-// members of an instance outside its
-// lifetime. (SynchronizationStorage::get() access non-static members)
-//
-// So, LinkerInitialized object of SynchronizationStorage uses a
-// non-trivial constructor, which is called at some point during dynamic
-// initialization, and is therefore subject to order of dynamic
-// initialization bugs, where get() is called before the object's
-// constructor is, resulting in undefined behavior.
-//
-// Similarly, a LinkerInitialized SynchronizationStorage object has a
-// non-trivial destructor, and so its lifetime ends at some point during
-// destruction of objects with static storage duration [basic.start.term]
-// p4. There is a window where other exit code could call get() after this
-// occurs, resulting in undefined behavior.
-//
-// Combined, these statements imply that LinkerInitialized instances
-// of SynchronizationStorage<T> rely on undefined behavior.
-//
-// However, in practice, the implementation works on all supported
-// compilers. Specifically, we rely on:
-//
-// a) zero-initialization being sufficient to initialize
-// LinkerInitialized instances for the purposes of calling
-// get(), regardless of when the constructor is called. This is
-// because the is_dynamic_ boolean is correctly zero-initialized to
-// false.
-//
-// b) the LinkerInitialized constructor is a NOP, and immaterial to
-// even to concurrent calls to get().
-//
-// c) the destructor being a NOP for LinkerInitialized objects
-// (guaranteed by a check for !is_dynamic_), and so any concurrent and
-// subsequent calls to get() functioning as if the destructor were not
-// called, by virtue of the instances' storage remaining valid after the
-// destructor runs.
-//
-// d) That a-c apply transitively when SynchronizationStorage<T> is the
-// only member of a class allocated in static storage.
-//
-// Nothing in the language standard guarantees that a-d hold.  In practice,
-// these hold in all supported compilers.
-//
-// Future direction:
-//
-// Ideally, we would simply use std::mutex or a similar class, which when
-// allocated statically would support use immediately after static
-// initialization up until static storage is reclaimed (i.e. the properties
-// we require of all "linker initialized" instances).
-//
-// Regarding construction in static storage, std::mutex is required to
-// provide a constexpr default constructor [thread.mutex.class], which
-// ensures the instance's lifetime begins with static initialization
-// [basic.start.init], and so is immune to any problems caused by the order
-// of dynamic initialization. However, as of this writing Microsoft's
-// Visual Studio does not provide a constexpr constructor for std::mutex.
-// See
-// https://blogs.msdn.microsoft.com/vcblog/2015/06/02/constexpr-complete-for-vs-2015-rtm-c11-compiler-c17-stl/
-//
-// Regarding destruction of instances in static storage, [basic.life] does
-// say an object ends when storage in which the occupies is released, in
-// the case of non-trivial destructor. However, std::mutex is not specified
-// to have a trivial destructor.
-//
-// So, we would need a class with a constexpr default constructor and a
-// trivial destructor. Today, we can achieve neither desired property using
-// std::mutex directly.
