Comment (by mabshoff):

 For the record: Patch applies, builds fine and all doctests with -long
 pass. The performance regression seems to have been fixed, i.e. before:
 {{{
 sage -t -long "devel/sage/sage/modular/modform/eisenstein_submodule.py"
          [73.3 s]
 }}}
 After the patch:
 {{{
 sage -t -long "devel/sage/sage/modular/modform/eisenstein_submodule.py"
          [3.4 s]
 }}}

 Cheers,

 Michael
