---------------------------------------
This is an old issue but could lead to unexpected behaviors even in the current
version. I created a [PR|https://github.com/apache/flume/pull/369] for that.
Could someone review this?

> flume-taildir-source stored the matched files in
> _ReliableTaildirEventReader.tailFiles_, and updated it in
> _ReliableTaildirEventReader.updateTailFiles()_, which will be invoked in the
> main thread(_TaildirSource.process()_). But at the same time,
> _ReliableTaildirEventReader.tailFiles_ will be read in the _idleFileChecker_
> thread and _PositionWriter_ thread, will there be any race condition?
