There is a potential memory leak in `Workerpool` due to the intricacies of `time.Timer` stopping. Whenever a `time.Timer` is `Stop`ped its channel must be cleared using a `select` if the result of the `Stop()` is `false`. Unfortunately in `Workerpool` these were checked the wrong way round. However, there were a few other places that were not being checked.
