+ * Asynchronous operations may need to allocate temporary objects. Since
+ * asynchronous operations have a handler function object, these temporary
+ * objects can be said to be associated with the handler.
+ *
+ * Implement asio_handler_allocate and asio_handler_deallocate for your own
+ * handlers to provide custom allocation for these temporary objects.
+ *
+ * The default implementation of these allocation hooks uses <tt>::operator
+ * new</tt> and <tt>::operator delete</tt>.
+ *
+ * @note All temporary objects associated with a handler will be deallocated
+ * before the upcall to the handler is performed. This allows the same memory to
+ * be reused for a subsequent asynchronous operation initiated by the handler.
+ *
+ * @par Example
+ * @code
+ * class my_handler;
+ *
+ * void* asio_handler_allocate(std::size_t size, my_handler* context)
+ * {
+ *   return ::operator new(size);
+ * }
+ *
+ * void asio_handler_deallocate(void* pointer, std::size_t size,
+ *     my_handler* context)
+ * {
+ *   ::operator delete(pointer);
+ * }
+ * @endcode
