Some more data points:

v6 patch, with my laptop plugged directly into the gigabit ethernet
switch which is connected to the web server:

 - Worked perfectly 5 times in a row.

v6 patch, with my laptop next to the wifi aerial:

 - Bug is harder to reproduce, maybe only happens 50% of runs.

v6 patch, with my laptop about 100' from the wifi aerial:

 - Bug reproduces on every run.

So something to do with long latency links.

Question: Is there a place in the patch we could put a sleep in order
to simulate a long latency link?

I also checked the logs on the web server.  There are no errors, and
each access returned a 200 or 206.  So the problem doesn't appear to
be at the web server end.
