does petsc currently support QR factorization?
I saw that it is supposedly provided by an interface to the spooles  
package, however the comment in MatQRFactorSymbolic_SeqAIJSpooles  
that says
SETERRQ(PETSC_ERR_SUP,"QR Factorization is unsupported as the Spooles  
implementation of QR is invalid.");
seems to imply that it is not working.
