> This has to do with query cancelation and I thought that the way Lucene 4
> implemented query rewrites this would not be needed anymore. However I was
> wrong. During leading wildcard queries the all the terms of a field have to
> be traversed and if the field is very large this can cause a lot of
> processing to occur. During this term iteration if the query is canceled or
> it timeouts the thread has no way of exiting the iteration loop.
> The ExitableReader provides a lightweight wrapper around a standard
> DirectoryReader and will throw an exception once the internal AtomicBoolean
> is set to false.
