Comment:
The patch `trac_7123-iter.patch` looks good. Doctesting the whole Sage
library, the only failure I got is the following:
{{{
sage -t -long devel/sage/sage/modules/vector_double_dense.pyx
**********************************************************************
File "/scratch/mvngu/sage-4.2.alpha0-sage.math/devel/sage-
main/sage/modules/vector_double_dense.pyx", line 663:
sage: v.stats_kurtosis()
Expected:
-1.23
Got:
doctest:106: SyntaxWarning: assertion is always true, perhaps remove
parentheses?
-1.23

}}}
This doctest passed on a second try.
