I had to make the sleep shorter on my system. Looking...
The PostmasterStateMachine() case for PM_WAIT_BACKENDS doesn't tell the checkpointer to shut down in this race case. We have CheckpointerPID != 0 (because 7ff23c6d27 starts it earlier than before), and FatalError is true because a child recently crashed and we haven't yet received the PMSIGNAL_RECOVERY_STARTED handler that would clear it. Hmm.
