New description:

 In `src/sage/modules/vector_double_dense.pyx` there is a lot of code like
 {{{
         global numpy
         if numpy is None:
             import numpy
 }}}

 However, since the whole module is not imported at startup, we might as
 well just put a global
 {{{
 cimport numpy
 import numpy
 }}}
 and be done with it.
