Well, I don't really see any problem with option B.  It gives the best of both worlds: it works in Jython, but we still get the optimization in CPython.  It would be a little better if we could test against the behavior itself rather than against if we are in Jython or not, but I have no idea what is going on here, so I wouldn't know how to do that.

See the SymPy issue for a patch that fixes this.  Unfortunately, now that we can import sympy in jython, there are a ton of test failures, so we still may require assistance in fixing things (which is much appreaciated, by the way).
