 Oh, well that is good to know. I'll be able to use them up a lot
 quicker next time.

 Yes, I have confirmed tons of fontconfig files, about 6 per rrdtool db table.
 Given 63 separate metric tables, and 388 new fontconfig cache files per graph
 rendering, invoked from cron every 8 minutes. That explains the inode
 consumption.
 
 I'll open a separate PR for rrd tool. This one can be closed. Thank you!
