SYMPOW-related doctests can in
sage/lfunctions/sympow.py sage/modular/abvar/abvar.py sage/modular/hecke/submodule.py sage/schemes/elliptic_curves/ell_rational_field.py
can fail if users who do not have write access under SAGE_ROOT runs these tests before a user who does have this access.
This is the likely cause of the non-qepcad failures reported by Luis Felipe Tabera on sage-devel.
