Great, I'm glad you've found the problem, and also pleased that it's not
a locking issue.  This should be much easier to fix, and as there were
changes to tcp_enqueue in 1.3.1 also explains why this problem is new.
Could you please file a bug?

To answer your question, the fix will be to fix tcp_enqueue to not
concatenate non-consecutive segments.
