You have to make sure that no concurrent calls can occur to member 
functions of the same socket class. This may be achieved by serializing 
your read/writes/read handlers/write handlers through a strand.

In case of large buffers, Asio may split up an async_write() operation 
into several async_write_some operations (often referred to as "composed 
operations").
