The spin decomposition of the proton is a long-standing topic of much interest in hadronic physics. Lattice QCD has had much success in calculating the connected contributions to the quark spin. However complete calculations, which necessarily involve gluonic and strange-quark contributions, still present some challenges. These ``disconnected'' contributions typically involve small signals hidden against large statistical backgrounds and rely on computationally intensive stochastic techniques. I
