;; there can be multiple servers spawned for the same runid.  we want exactly zero or one servers per runid.  The caller is a nascent server.  It wants to know if it should proceed or if it is redundant.  this function chooses a winner and tells me if I am the winner.  Alternative is lots of runaway servers.  Nobody wants that, trust me.
;;
;; algo: get all server info entries for this runid.  Each nascent server will insert an entry for its runid before getting here.  Entries are visible globally.  If current hostname and current processid match first entry, then yes I am the server;  return server-id as my prize for winning.  Otherwise, I am not the server;  return #f.
