[boost] [asio] wrapping handler with tuple in serialization example, client.cpp, connection.hpp

In svn, the serialization example wraps a mem func ptr in a tuple to
be tossed through various bind calls.

In client.cpp, I found that using boost::protect around the bind call
prevents the compile errors but I'm not sure why.

connection_.async_read(stocks_,
           boost::protect(boost::bind(&client::handle_read, this,
            boost::asio::placeholders::error)));

Any ideas as to why this works?
