I'm not surprized, I remember about tux on 2.4 sometimes leaving frozen
connections behind it when pushed to extreme speeds back in the days where
it was audacious to pull 2 Gbps out of a Pentium3.

I like it when we find very old issues when improving the code, it generally
means we're stressing it a bit more and making more efficient use of it.

Cheers,
Willy
