	Basically, what the OP said, is that we need readers-writer locks
[1]. A const synchronized method would use the read lock (and
therefore several threads can access the same object through *const*
synchronized methods simultaneously), but a non const synchronized
method would use the read-write lock (which would prevent anyone
else from accessing the same object through a synchronized method,
be it const or not).
