Comment:
patch [attachment:7879-RR-signal.2.patch] applied to sage-4.7.1.alpha1.
Then did 'sage -b' followed by 'make testlong'.
The following test failed:
{{{
eno% ./sage -t -long -force_lib "devel/sage/sage/rings/residue_field.pyx"
sage -t -long -force_lib "devel/sage/sage/rings/residue_field.pyx"
