A small bug fix related to appending solutions is included in this commit.

The benchmarks show, surprisingly, a more noticeable improvement for larger solvers (h10, h11). I was expecting it to be more noticeable for smaller solvers. It is likely that this change is irrelevant to performance and all changes in the benchmark results are just random chance.
