Well, I tried the patch in version 6.4.rc2. My original program now runs
fine. There, however, all MIPs are feasible. So I tried a silly test code
where every other MIP is infeasible. Again, memory usage is constant.
So the Coin and gurobi backends now seem to work fine.
(By the way, MIPSolverException cannot be used in a try/except
environment. Not sure if this is a bug. Anyway, this was the same in the
unpatched version.)
