…ls to _get_topology

The benchmarks don't show much improvement but I believe that's because they don't yet cover the case where there's many threads contending for the topology lock. Locally I see a ~10% improvement on find_one() and ~15% improvement on db.command() on a benchmark with 30-100 threads. |
