The delay is caused because some Commands are only called in certain interval(called refreshInterval, default, 1000ms). In aria2 download stops when all Commands associated to it are stopped. Since some Commands are called in each 1000ms by default, as mentioned before, we have to wait for them. To fix this issue, we call DownloadEngine::setRefreshInterval(0) when pausing/stopping downloads. DownloadEngine::setRefreshInterval(0) makes refreshInterval 0 in one shot. When all segments are ignored, now DownloadFailureException is thrown. And stop the download immediately. As described earlier, we call DownloadEngine::setRefreshInterval(0) in catch block of DownloadFailureException to eliminate delay.
