* concurrent echo client for stress testing * update examples for benchmarking, tweak cabal file * mark frequently-used call as unsafe for performance boost * add unsafe annotation to non-blocking C calls on critical path * more unsafe annotations -- server performance almost doubled now * one CQ for all call ops * unsafe annotation on start_batch * wait for all client threads, replace error with fail * add -O2
