Subject: [PATCH] runtornado: Remove ability to run without specifying exactly
 one port

The zero-port case never actually worked, because addrport wasn't an optional
parameter in run_one.  And multiple ports was implemented using the
multiprocessing library, which is just bad news.  Since we have no need for
this, remove it before it can cause trouble.
