I just cannot reproduce on my GNU/Linux Debian box (a dual-core). I'll
try later today
on a quad core.

I have even pushed the number of simultaneous clients to 8 and sending
100000 requests.

HTML transferred is correct and on the AWS side:

$ grep "200" hello_world-2011-01-25.log | wc
 100000  900000 6100000

$ grep "200 16" hello_world-2011-01-25.log | wc
 100000  900000 6100000
