> The typical workflow for deleting an LSM index is to deactive, purge, and
> destroy. During deactive, we close the file. Then during purge, we should
> remove the file mapping and all file pages. Finally, during destroy, the file
> is physically deleted. However, BufferCache.purge didn't clear cached pages
> as specified. Even though delete file internally calls clear pages, which is
> never executed since the file mapping has already been removed. As a result,
> files pages are not removed even though the file is deleted.
