// This header can get included by boost/shared_ptr.hpp which leads
// to cyclic dependencies, the workaround is to forward declare all 
// the boost components, and then include the actual headers afterwards.
// This is fragile, but seems to work, and doesn't require modification
// of boost/shared_ptr.hpp.
