kgo may have been referring to how the contents of /private/tmp, /private/var/log and /private/var/tmp are not encrypted and may contain private information, such as com.apple.QuickLook.thumbnailcache.

I've had some success using scripts on the following website to plug these holes, but recently, I have been more concerned with my data's survivability than my privacy. Once that grad degree is done, I hope to return to a more secure approach.
