1.) do you know that boost.asio integrates boost.coroutine? example can be
read at
http://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/example/cpp03/spawn/echo_server.cpp
2.) coroutine<> is a type holder, e.g. you have to derive from
coroutine<>::push_type or coroutine<>::pull_type
3.) usually you would not track SimpleObj as is-a-coroutine -> I suggest to
aggregate coroutine<> instead derive from it
