nanosleep(2) uses "high resolution" so I think we should be consistent with that. > - The current manual mentions an upper bound (2147483647).

This may have been copy pasta from alarm.3 which used to document the same limit (which was actually incorrect at the time due to itimerfix). > I am leaning toward just leaving the patch as-is instead of trying > to guide the end-user through the minefield of matching bespoke > "_t" types to real types and limits. > > Tweaks? ok?
