-// WARNING: Thread local storage is a bit tricky to get right.  Please make
-// sure that this is really the proper solution for what you're trying to
-// achieve.  Don't prematurely optimize, most likely you can just use a Lock.
-//
-// These classes implement a wrapper around the platform's TLS storage
-// mechanism.  On construction, they will allocate a TLS slot, and free the
-// TLS slot on destruction.  No memory management (creation or destruction) is
-// handled.  This means for uses of ThreadLocalPointer, you must correctly
-// manage the memory yourself, these classes will not destroy the pointer for
-// you.  There are no at-thread-exit actions taken by these classes.
-//
-// ThreadLocalPointer<Type> wraps a Type*.  It performs no creation or
-// destruction, so memory management must be handled elsewhere.  The first call
-// to Get() on a thread will return NULL.  You can update the pointer with a
-// call to Set().
-//
-// ThreadLocalBoolean wraps a bool.  It will default to false if it has never
-// been set otherwise with Set().
-//
-// Thread Safety:  An instance of ThreadLocalStorage is completely thread safe
-// once it has been created.  If you want to dynamically create an instance,
-// you must of course properly deal with safety and race conditions.  This
-// means a function-level static initializer is generally inappropiate.
-//
-// In Android, the system TLS is limited, the implementation is backed with
-// ThreadLocalStorage.
-//
-// Example usage:
-//   // My class is logically attached to a single thread.  We cache a pointer
-//   // on the thread it was created on, so we can implement current().
-//   MyClass::MyClass() {
-//     DCHECK(Singleton<ThreadLocalPointer<MyClass> >::get()->Get() == NULL);
-//     Singleton<ThreadLocalPointer<MyClass> >::get()->Set(this);
-//   }
-//
-//   MyClass::~MyClass() {
-//     DCHECK(Singleton<ThreadLocalPointer<MyClass> >::get()->Get() != NULL);
-//     Singleton<ThreadLocalPointer<MyClass> >::get()->Set(NULL);
-//   }
-//
-//   // Return the current MyClass associated with the calling thread, can be
-//   // NULL if there isn't a MyClass associated.
-//   MyClass* MyClass::current() {
-//     return Singleton<ThreadLocalPointer<MyClass> >::get()->Get();
-//   }
