Makes sense if the server has a plan *when* it intends
to purge pending triplets.  And <max-secs> certainly
could need more than 6 digits; and my suggestion that
6 digits fit into an ushort works only in a parallel
universe with "ternary bits" where they'll use Ipv4
forever squeezing three digits 0, 1, and "" (void) in
a single bit...
