+   *  @brief  The "standard" allocator, as per [20.4].
+   *
+   *  The private _Alloc is "SGI" style.  (See comments at the top
+   *  of stl_alloc.h.)
+   *
+   *  The underlying allocator behaves as follows.
+   *    - __default_alloc_template is used via two typedefs
+   *    - "__single_client_alloc" typedef does no locking for threads
+   *    - "__alloc" typedef is threadsafe via the locks
+   *    - __new_alloc is used for memory requests
+   *
+   *  (See @link Allocators allocators info @endlink for more.)
