Nah, not worth the effort. time_wait sockets are good to try to follow the rules on, but if the choice is to delay or throw away one prematurely, throwing one away prematurely is the better choice. > Anyway, I'm strongly against doing the purge cycling in the syscalls. Yep, me too - doing purge cycling was never my intent; it was just supposed to be a last ditch attempt to free a time_wait socket that was taking up an ephemeral port when no ephemeral ports were left.
