Probably the easiest way (without leaving scents) is to use another person's claim (who you might not trust with your key). Have your alt stand on his claim, make him revoke permissions for your alt and close the alt's client or use :lo (not :act lo, since you won't actually be logging out). You can now log in on your main character, since the alt cannot log out from a claim he has no permissions on.
You can do this on your own claim too, by having the alt stand in boston, remove his permissions, teleport him to his leanto which is on your main's claim (and on which the alt no longer has permissions), and then continue as above. As soon as you re-enable permissions, the alt will automatically log out again.
