Screen Sharing Forever


If you have two macs and absolutely nothing to do, try turning on screen sharing on both macs, then gaze the desktop of the other mac, and from that mac, select screen sharing back to the mac you are using.. what happens is.. well, logical..

(Be warned, it is difficult if not impossible to recover from this infinity trap. It is not possible to turn off screen sharing once this loopback is established. Only way for me to recover from this for me was to do a hard boot.)
