The ground truth here is that this problem is unique to you and no one
else has ever reported anything remotely similar. It is not a Mercurial
issue, it is your issue. I've already invested too much time in this,
and it's not a good use of my time to debug this any further by
guessing.

Recommend you systematically rule out each component and config option
of your system as the cause. In my first email, I mentioned using 'hg
serve' to test your repo on my laptop. You can do the same on your
server. If it works, you will have thus proven that the problem is not
in your Mercurial install, but in your web server configuration. Or vice
versa.
