I have implemented JDSDirectory that stores Lucene indices in JDataStore database from Borland. JDataStore implements FS-like storage, where SQL tables are just "files" of type "table". They do have transaction management, but I do not know if it covers any file type or only tables, I haven't make any testing yet. If you want, I can send this implementation to you. This might solve your problem, because there's no file handles involved, if TxManager spans the whole database, you get ACID properties there. The drawbacks are that JDataStore is not for free (there's very funny licensing involved, sometimes $100 USD, sometimes $1,000 or more) and I haven't tested it with big databases (but Borland claims to support couple of terabytes :)). Speed was similar to FSDirectory in my tests (difference of ~5-10% max.). I was thinking of posting it to Lucene contributions, but recently got completely different task and have no time to check if the code is clean enough to make it public.
