Ilpo's cleanup (the second commit listed) looks most likely to
be a possibility.
But I surely cannot find any bugs in it, even after studying it
a few times.
Ilpo could you audit it one more time for us just in case?
I also looked through all the TCP commits in 2.6.29 to 2.6.30
and I could not find anything else that might cause stalls with
time-wait recycled connections.
