According to CVS the documentation was added in August 2007.

It's been online for quite a long time as well.
http://www.openldap.org/software/man.cgi?query=slapd-bdb&sektion=5&apropos=0&manpath=OpenLDAP+2.4-Release

Another point is that the cache configurations are based on a specific number 
of items, and not on the size of each item in bytes. If you have particularly 
large entries or long DNs then you'll have greater memory use as well.
