keepalive_timeout not working?

keepalives seem to be working, but the timeout limit I'm setting isn't
honored it seems.. Someone let me know if I've done something wrong or
am missing something.

I have nginx installed on Ubuntu from the stable repository at
nginx.org. Nothing has been added, nothing removed.

==================================
nginx version: nginx/1.4.2
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx
--conf-path=/etc/nginx/nginx.conf
--error-log-path=/var/log/nginx/error.log
--http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid
--lock-path=/var/run/nginx.lock
--http-client-body-temp-path=/var/cache/nginx/client_temp
--http-proxy-temp-path=/var/cache/nginx/proxy_temp
--http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp
--http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp
--http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx
--group=nginx --with-http_ssl_module --with-http_realip_module
--with-http_addition_module --with-http_sub_module
--with-http_dav_module --with-http_flv_module --with-http_mp4_module
--with-http_gunzip_module --with-http_gzip_static_module
--with-http_random_index_module --with-http_secure_link_module
--with-http_stub_status_module --with-mail --with-mail_ssl_module
--with-file-aio --with-http_spdy_module --with-cc-opt='-g -O2
-fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security
-Werror=format-security -Wp,-D_FORTIFY_SOURCE=2'
--with-ld-opt='-Wl,-Bsymbolic-functions -Wl,-z,relro' --with-ipv6
=================================

In my http block, I have the following.

keepalive_timeout 3s;

That is the only place the string 'keepalive' exists.

=================================
root@web:/etc# grep -r "keepali" .
grep: ./blkid.tab: No such file or directory
Binary file ./alternatives/rsh matches
Binary file ./alternatives/rlogin matches
../nginx/nginx.conf: keepalive_timeout 3s;
=================================

Yet, when I take a look at netstat -tc, I have waay too many http
connections in a TIME_WAIT state and they seemingly stay there forever.
Obviously it's not forever, but it's not closing in 3 seconds.

Thanks.
