Yes. The code dates from the 80s and it is pretty well shaken out :-)
And, more or less if the TCP code were buggy (other than not quite
retransmitting on the right schedule to exactly meet the congestion
control specs) sort of thing, it would show up and would have been
fixed. This could be the one thing that trips a bug, but that seems
unlikely.
