The times for close_delay and closing_wait are in hundredths of a

to use millisecond values (which would have to be rounded).

If you'd prefer, I can fold the second part of this into my previous
patch which shouldn't have documented it as milliseconds in the first
place (but I copied it from the other entry).

Could you send these two hunks as a separate patch? It's correct regardless of your other patch.

And I would use "centiseconds" instead, which is used (IMO) in these cases.
