Tagged union containing either a read_request or a write_request.
In C++11, this can be implemented more elegantly since the C++11 standard allows unions with member types having constructors and destructors. In C++03, we have to emulate this with a char buffer that is large enough.
To turn the tagged union into a T, call set_T(ctor params) which returns a reference to T. When the tagged union is a T (check with kind()), use get_T() to get the reference to T.
