> ServerManager#onlineServers is a ConcurrentHashMap
> Yet I found that some accesses to it are synchronized and unnecessary.
> Here is one example:
> {code}
>   public Map<ServerName, ServerLoad> getOnlineServers() {
>     // Presumption is that iterating the returned Map is OK.
>     synchronized (this.onlineServers) {
>       return Collections.unmodifiableMap(this.onlineServers);
> {code}
> Note: not all accesses to ServerManager#onlineServers are synchronized.
