Comment(by ncohen):
> So the problem seems to be the Coin patch in this case. I'll look for
how to fix it, but if you have suggestions, let me know.
Well, I usually fix this twice : by relacing the ``==1`` in the return
value by of the method building the LP by a ``>.5``, and by adding a "if
the variabe is binary, round it before returning it" in the functon
returning the values of variables in the solver backends.
