Having just finished instrumenting tcp_output.c to track the problem
down, I find that it has vanished. It seems that it was fixed
sometime between 3rd August and last night. The only change to
tcp_output.c during this time was v1.46 - which only affects error
behaviour and backing that change out had no effect (ie the problem
is still gone). I don't recall seeing any commits that would have
affected this problem.
