Sometimes the `/stats` can report a negative number of active browsers

# curl http://192.1.1.1:8080/stats
{"active_connections": -75, "connection_count_total": 9477, "dropped_threshold_reached": 0, "dropped_waited_too_long": 126, "mem_use_percent": 54.7, "special_counter_len": 0}

Maybe dropped_waited_too_long doesnt handle it properly?
