New description:
We correct
{{{
sage: import numpy
sage: numpy.int32(123) == 123
True
sage: 123 == numpy.int32(123)
False
}}}
The change causes numpy to be loaded on startup. It may be hard to not do
it as there are many integer comparisons on startup (see
[http://trac.sagemath.org/sage_trac/ticket/13386#no3 see nbruin comment]).
