      In performance testing the ServiceEntryPoint benchmark, which basically just calls the ping command, we see that a good chunk of time is spent in getLockerInfo. We spend 3% of the total time in the benchmark inside this function, mostly downstream of CurOp::_sumBlockedTimeTotal(), but in other areas as well.

      See if there are any potential ways to cache info here, or make this algorithmically tighter (do we need to emplace items into a vector then std::sort them?)
