FSDirectory.sync(String name) is the lowest level.

That's called from IndexWriter.startCommit() and then
SegmentInfos.finishCommit() to flush the segment file.

That's hairy code... I imagine we may want to just use the code from
FSDirectory.sync() and make our own sync service based on an executor.
It seems like we would want to throw a file to the sync executor as
soon as we've downloaded it.  Then wait until all files are sync'd
before moving everything out of the temp directory.
