I'd just drop all mention of the pool lifetime, documenting that it is
"unimportant" is a bit silly. Don't mention the deep-copy either,
it's an implementation detail. In general if functions don't mention
lifetime then it should be safe to assume that the parameters doesn't
need to live beyond the function call.
