One is to add a periodical checker as a safe net for the behavioural 
optimization change in previous set (from exhaustively scanning all the rings 
to only checking targeted ones). The consideration here is that there might be 
some ill-behaved clients currently existing in the wild, so it's better to make 
gradual move.

The other one is a performance improvement related to syslog. Currently, if 
configured to use syslog, every single line of access log could potentially 
call sys.stat 3 times, which is a considerable cost given the intensiveness of 
our access logging.

As the first patch is close related to the some feature in the previous set (as 
a safety improvement), it's better to just wait a little bit.

Thanks,
