o TCP_USER_TIMEOUT for the local timeout seems fine. This is consistent

with the literature and everybody knows how to interpret such a variable.



o TCP_ADV_UTO for the announced timeout. It correspond with the RFC and

inherent the word "advertise".



Jerry, for you the former is of interest, you can completely ignore my

on-top-functionality. I am satisfied with this!



Cheers, Hagen
