> Today, rollback() doesn't always succeed: if it does, it closes the writer
> nicely. otherwise, if it hits exception, it leaves you with a half-broken
> writer, still potentially holding file handles and write lock.
> This is especially bad if you use Native locks, because you are kind of
> hosed, the static map prevents you from forcefully unlocking (e.g.
> IndexWriter.unlock) so you have no real course of action to try to recover.
> If rollback() hits exception, it should still deliver the exception, but
> release things (e.g. like IOUtils.close).
