If another thread is executing a query with the handle to one of readers[i]
you're going to kill it since the IndexReader is now closed.
Just don't call the IndexReader#close() method. If nothing is pointing at
the readers they should be garbage collected. Also, you might
want to warm up your new IndexSearcher before you switch to it, meaning run
a few queries on it before you swap the old one out.
