I just posted the third article about my comet experiments, which covers
why I needed to patch libevent to open >1M connections:

Hi,
In order to open more than 2^16 connections (HTTP connections in my
case) *from* one machine, you need to use multiple local IPs, because
the maximum local port number is 65536.
evhttp_connection_set_local_address already exists and is suitable for
this.
The ephemeral port allocator, which is
