...70// the number of VUs that are simultaneously running.

For reasons of ease of76// implementation and lack of good evidence it's not required to let a not started iteration to77// finish in other words if you call start and then gracefulStop, there is no requirement for78// 1 iteration to have been started.79// - hardStop must stop an iteration in process80// - it's not required but preferable, if where possible to not reactivate VUs and to reuse context81// as this speed ups the execution82type vuHandle struct {83	mutex                 *sync.Mutex84	parentCtx             context.Context85	getVU                 func() (lib.InitializedVU, error)86	returnVU              func(lib.InitializedVU)87	nextIterationCounters func() (uint64, uint64)88	config                *BaseConfig89	initVU       lib.InitializedVU90	activeVU     lib.ActiveVU91	canStartIter chan struct{}92	state stateType // see the table above for meanings93	// stateH []int32 // helper for debugging94	ctx    context.Context95	cancel func()96	logger *logrus.Entry97}98func newStoppedVUHandle(99	parentCtx context.Context, getVU func() (lib.InitializedVU, error),100	returnVU func(lib.InitializedVU),101	nextIterationCounters func() (uint64, uint64),102	config *BaseConfig, logger *logrus.Entry,103) *vuHandle {104	ctx, cancel := context.WithCancel(parentCtx)105	return &vuHandle{106		mutex:                 &sync.Mutex{},107		parentCtx:             parentCtx,108		getVU:                 getVU,109		nextIterationCounters: nextIterationCounters,110		config:                config,111		canStartIter: make(chan struct{}),112		state:        stopped,113		ctx:      ctx,114		cancel:   cancel,115		logger:   logger,116		returnVU: returnVU,117	}118}119func (vh *vuHandle) start() (err error) {120	vh.mutex.Lock()121	defer vh.mutex.Unlock()122	switch vh.state {123	case starting, running:124		return nil // nothing to do125	case toGracefulStop: // we raced with the loop, lets not return the vu just to get it back126		vh.logger.Debug("Start")127		close(vh.canStartIter)128		vh.changeState(running)129	case stopped, toHardStop: // we need to reactivate the VU and remake the context for it130		vh.logger.Debug("Start")131		vh.initVU, err = vh.getVU()132		if err != nil {133			return err134		}135		vh.activeVU = vh.initVU.Activate(getVUActivationParams(136			vh.ctx, *vh.config, vh.returnVU, vh.nextIterationCounters))137		close(vh.canStartIter)138		vh.changeState(starting)139	}140	return nil141}142// just a helper function for debugging143func (vh *vuHandle) changeState(newState stateType) {144	// vh.stateH = append(vh.stateH, newState)145	atomic.StoreInt32((*int32)(&vh.state), int32(newState))146}147func (vh *vuHandle) gracefulStop() {148	vh.mutex.Lock()149	defer vh.mutex.Unlock()150	switch vh.state {...
