Follow-up Comment #1:

Fixed, thanks for reporting.

In addition to the suggested fix, I've flushed the entry right in the
receive-callback, which is what RFC 883 requires on page 29:

"Zero values are
interpreted to mean that the RR can only be used for the
transaction in progress, and should not be cached."
