warning message in standby

Hi,

When an error is found in the WAL streamed from the master, a warning
message is repeated without interval forever in the standby. This
consumes CPU load very much, and would interfere with read-only queries.
To fix this problem, we should add a sleep into emode_for_corrupt_record()
or somewhere? Or we should stop walreceiver and retry to read WAL from
pg_xlog or the archive?

Regards,
