Description
version 1.7.6
采用的FileDownloadQueueSet来执行的多任务的串行下载。大概10%左右的概率出现长时间没有任何回调，开始以为任务出错了，或者完成了没有回调。
但是抓到一个日志， 其实并没有结束。而是四分钟之后才开始有回调。
[D][2018-08-14 +8.0 15:15:17.092][32302, 3809][FileDownloader.MessageSnapshotGate][updateKeepFlow
------中间隔了四分钟
[D][2018-08-14 +8.0 15:19:01.137][32302, 3815][FileDownloader.FetchDataTask][require flushAndSync id[757008789] index[0] offset[2115874], consume[6]
完整日志尝试很久上传。 但是一直穿不成功。

Research direction
Start by tracing the FileDownloadQueueSet flow through FileDownloader.MessageSnapshotGate and FileDownloader.FetchDataTask, using the supplied timestamps and the four-minute callback gap as the reproduction symptom. Determine where queued downloads stop reporting progress, completion, or errors, and verify that callbacks resume promptly without delaying the download.
