I think I could reproduce the same issue, with and whithout nginx, with this
short configuration sample (with KeepAliveTimeout 15 on the apache backend) :
listen close_test :8080
mode http
option httpclose
option http-pretend-keepalive
server www localhost:80
listen tunnel_test :8081
mode http
option http-pretend-keepalive
server www localhost:80
Both have problems nginx (unless I disabled buffering in nginx).
But it's also reproducible with ab :
$ ab -n1 http://localhost:8080/
Time taken for tests: 15.017 seconds
$ ab -n1 http://localhost:8081/
Time taken for tests: 15.016 seconds
$ ab -n1 http://localhost:8082/
Time taken for tests: 15.016 seconds
It appeared with this commit :

Willy, can you review the patch below to see if it's the right approach ?
Thanks ;-)
