I think bulk-import of posts/content trigger "cache purge" codes. We might need to change hooks to avoid this.

WP_IMPORTING constant set when we import content using WordPress Importer plugin. I believe this constant also set by any other importer plugin. So if this constant defined and its value is true then we won't purge. We will think of any other ways.
