Michael McCandless updated LUCENE-6616:
---------------------------------------
    Attachment: LUCENE-6616.patch

New patch, I think it's ready.

I reviewed the places where I now call IFD.deleteNewFiles, and except for one case (which I fixed) the files we pass are all files that we have written.  So I think it's safe.

I also added an assert in IFD where it actually deletes the file that if it hits an IOExc, it is NOT a NoSuchFileExc nor FNFE, which may (not guaranteed!) be thrown when you try to delete a non-existent file.
