> I have implemented index distribution/replication mechanism using NTFS hard links.  I make a hard-link copy of my index files into another directory on a one-minute interval.  The problem is that deleting older snapshot files index is impossible because NTFS hard-links will not delete if another program currently has ANY other link to the same file open without concurrent delete share option.  This is solvable by adding the System.IO.FileShare.Delete option to FSIndexInput and FSIndexOutput classes.  This should not have any negative impact on existing Lucene indexes I dont think.
