Many times while the initial connection is being made, the contacted partition will send back both the ACTIVATING and the ACTIVE remote_act_state changes in very close succescion. The 1/4 second delay in the make first contact loop is large enough to nearly always miss the ACTIVATING state change. Since either state indicates the remote partition has acknowledged our state change, accept either.
