Comment:

 With the new patch, I get these errors using sage -testall on an
 imac running 10.6.1 and sage-4.3.a1:

 {{{

 In particular, there are possibly these new errors:


 {{{
         sage -t  "devel/sage/sage/graphs/base/dense_graph.pyx"
         sage -t  "devel/sage/sage/graphs/graph.py"
         sage -t  "devel/sage/sage/graphs/graph_generators.py"
         sage -t
 "devel/sage/sage/groups/perm_gps/partn_ref/refinement_graphs.pyx"
         sage -t  "devel/sage/sage/homology/simplicial_complex.py"
         sage -t  "devel/sage/sage/structure/sage_object.pyx"
 }}}
 I did not check of the output from the graph_generators.py test was the
 same before and after the patch. So some of these failures might be
 unrelated. It does seem as though the test for refinement_graphs.pyx
 hangs. That alone seems to be a problem, doesn't it?
