The reason cached terminologies are useful is because *asking* for 
terminologies is slow.  If you have to ask if it's updated, you might 
as well not have cached it in the first place.  If you don't ask if 
it's updated, then it's impossible to know for sure whether or not your 
cached terminology is stale.
