This looks likely to be correct since when we exit in WalReceiverMain() 
(on WALRCV_STOPPING and WALRCV_STOPPED) we call proc_exit(1). I feel we 
should exit the same way in WalRcvWaitForStartPosition() as we do in 
WalReceiverMain() and if not I would like a comment explaining why those 
two cases are different.
