Indexers never closed

[Andy Armstrong]

I'm currently attempting to add a Lucene based full text indexer to 
Xindice 1.1b3. A Lucene index needs to be explicitly closed but it seems 
that, certainly in embedded mode, an indexer's close() method never gets 
called so I don't get to close my Lucene index. It'll be fairly simple 
to add I think but I'm wondering if I'm missing something important :)
