You point out corner cases where things might go wrong. All protocols 
have that, starting from the fact that we normally employ best-effort 
transimission technologies, and hence there are no reliability warrants. 
And what I've mentioned is that even in such scenarios, one can be even 
more conservative if one wanted. -- For instance, I don't mind 
LTA_INVALID being 1800 sends, if that's the show stopper. Or even double 
that.

Performance does not get any worse. If anything, it takes longer to 
*garbage-collect* stale addresses. The high order bit is that you want 
new communication instances to work asap. And this draft achieves that.

Your input is indeed heard. We did add a whole section in response to 
your feedback.

Thanks,
