> On Windows, which prevents deletion of still-open files, IndexWriter cannot remove files
that are in-use by open IndexReaders.  This is fine, and IndexWriter periodically retries
the delete, but it doesn't retry very often (only on open, on flushing a new segment, and
on committing a merge).  So it lacks immediacy.
> With this expert method, apps that want faster deletion can call this method.
