Ok, as an update of this topic, and for reference if anyone else have
the same problem, the solution is on the apache configuration side.
Nothing to do with web.py, which I just suspected.

To achieve this, I have disabled the keepAlive feature of Apache.
It prevent the browser to use a single connection to perform several
requests.
I tried to play with the keepalive parameters, but the symptoms where
still there.

After that, I was able to do a batch of 130 requests, from several
sources, without anything being lost in the void.
