   The reason for the vagueness is that persistDuration is

Yes, certainly.  That's what I was trying to say when I said:

By "when can" I meant "what is the earliest time at which it is OK to
remove it".  You might want to delay the actual "garbage collect"
in order to batch up deletes or in order to do it when load is low
or whatever.
