That\ncould later lead to a UAF.\n\nFix this by getting a reference early in the case where there is an\nextant confirmed client. If that fails then treat it as if there were no\nconfirmed client found at all.\n\nIn the case where the unconfirmed client is expiring, just fail and\nreturn the result from
