1) VS10 has && and std::move, but does not have the C++11 threading library.
   1b) A naive implementation (just starts a new OS thread) is not wanted.
   1c) but, an overly heavy implementation is not wanted either (i.e VS11 beta), because 
of additional dependencies in the program to distribute.
2) In the final code, the && will be optional, to avoid copies on compilers that support 
it, but must work with compilers that don't.
3) I need to preserve semantics of the code I'm replacing with modern C++ forms.

I don't understand how that applies to my compiler problem.  It's telling me that

            task_object(F const& f_);   // << refers to look here
            task_object(F&& f_);         // <<<< Error here

are not a valid overloading set and instead conflict.
