As Eric pointed out, changing tcp_ack()'s behavior effects state
transitions out of SYN_ACK, so this commit is very likely the culprit.

I usually see 2 or 3 three of these bug triggers in the first ten
minutes after bootup and I haven't seen one yet in 20 minutes
with the commit reverted.

This change is definitely wrong.
