See below, I only see one listening address in netstat.

I have listen *:80 before reload, then change it to listen one.local:80 and
reaload. nginx/1.2.6
Before reload:
callisto ~ # netstat -ntl | fgrep ':80'
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
After reload:
callisto ~ # netstat -ntl | fgrep ':80'
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
After restart:
callisto ~ # netstat -ntl | fgrep ':80'
tcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN
Did you have one.local and two local when you check this?
