I hit the following in the pg_basebackup tests just now, running on Linux:

    [08:41:21.621](0.377s) ok 196 - Walsender killed
    [09:09:11.134](1669.513s) # pump_until: timeout expired when
searching for "(?^:background process terminated unexpectedly)" with
stream: "pg_basebackup: error: unexpected termination of replication
stream: FATAL:  terminating connection due to administrator command
    # DETAIL:  Signal sent by PID 155573, UID 1000.
    # "
    [09:09:11.134](0.000s) not ok 197 - background process exit message
    [09:09:11.134](0.000s) #   Failed test 'background process exit message'
    #   at src/postgres/src/bin/pg_basebackup/t/010_pg_basebackup.pl line 1049.

But I haven't been able to reproduce since, so I don't know if this is
a new race, or the commit just exposed one that was there before?

Thanks,
