shows that the Cholesky factorization is computed ``too quickly''. 
152 

Can be a big pain for largish matrices, when it is unneeded.

 diag(m) < val currently automatically works via m[cbind(i,i)] < val 
155 

However, 
156 

we need methods for 'diag<' at least for diagonalMatrix, 
157 

triangularMatrix, and probably also "dense*general*Matrix" since the 
158 

above currently goes via "matrix" and back instead of using the 'x' slot 
159 

directly.
