I had tried something like this, but Cython complains:
{{{
sage/numerical/mip.pyx:281:13: Cannot delete C attribute of extension type
}}}
Is there a command that lets me delete the backend? I can see that there
is a command that is commented out, `void del_OsiCbcSolverInterface...`,
but I haven't yet figured out whether I should uncomment or use that.
