If we have multiple server blocks binding on https using SPDY, reuseport, and deferred nginx fails to start complaining about port already bound:

server {
listen 443 deferred ssl spdy reuseport;
server_name app.foo.com;
...
}

server {
listen 443 deferred ssl spdy reuseport;
server_name frontend.bar.com;
...
}

What is the behavior then if we change to:

server {
listen 443 deferred ssl spdy reuseport;
server_name app.foo.com;
...
}

server {
listen 443 ssl;
server_name frontend.bar.com;
...
}

Will both server blocks use SPDY, reuseport, and deferred, or only the first?
