Empty directories in SystemPageCache

Empty directories can grow under the SystemPageCache on the shared disk. This can contribute to unnecessary consumption of inodes in production where there is a high turnover of cached items. Cached pagelets are stored in subfolders under SystemPageCache, and when CS removes a pagelet the *.hdr, *.txt and *.qry files are deleted but the empty directories are not. These can be purged, preferably during a downtime.

E.g.;

find /path/to/SystemPageCache -type d -empty -depth -exec rmdir {} \;
