Yep, man pages are specs, and when the spec says tv may be modified by select(), that means you can't expect it to remain untouched. > Besides, given that most usages have no need for this, it would be a > wast of space and time. On the contrary, it is extremely useful for implementing higher-level timeouts. If you want to see the new installer come true, I need to implement protocol-level timeouts in libfetch, and that means either add a lot of gettimeofday() logic or fix select() to modify tv.
