Log with addresses + added fingerprint mechanism to avoid calling zombie objects where: - a message is sent with a receiver - the receiver dies - another receiver with the SAME address is created - the message reply is executed --> execution on the wrong object! (since their "identity" is their address. The fix is to identify them with an UUID stored at creation time)
