Comment (by nbruin):
The following is fishy in `coin_backend.pyx`:
{{{
def __cinit__(self, maximization = True):
...
self.si = new OsiClpSolverInterface()
self.model = new CbcModel(self.si[0])
...
def __dealloc__(self):
del self.si
}}}
If deleting `self.si` is required in dealloc, shouldn't `self.model` be
deleted as well? (this indicates to me that cython has grown enough
understanding of C++ to know how to translate a "del" on a C++ object?)
My money is on that we're leaking `CbcModel`s.
