* The exec count must be set to 0 before calling workerServer.fuzz. This was causing fuzz to run indefinitely after the first benchmark iteration, since it wouldn't hit the termination condition of being equal to fuzzArgs.Limit. * Added an assertion that the count must be lower than fuzzArgs.Limit at the beginning of workerServer.fuzz. * Also closed and deleted shared memory at the end of each benchmark run.
