If this was the final problem, this also explains why only some people are
seeing it. There are hardware platforms that are highly immune to this bug
(Michel Stol measured this), but we've seen an Openvirtuozo hosted Linux
being very vulnerable to it.
On my own testing hardware, the problem was relatively rare.
For the people who care, the root cause appeared to be doing non-atomic
updates to the TCP client count.
The release process for 3.3 can now start - only 1 feature request left to
