Comment:
For me at least, on !OpenSolaris with Mathematica 7.0.1, this is a
definite improvement, as it reduced the number of failures in
{{{devel/sage/sage/interfaces/mathematica.py}}} from 17 to 2.
== Prior to adding the patch ==
{{{
<snip out lots of failures>
4 items had failures:
5 of 84 in __main__.example_0
4 of 6 in __main__.example_1
4 of 19 in __main__.example_12
4 of 6 in __main__.example_2
***Test Failed*** 17 failures.

The following tests failed:

== After adding the patch ==
After applying the patch, the number of failures is reduced to 2.
