> Currently in 0.23 and trunk, there is no logging which indicates _why_ a replica has
been marked corrupt, only that it has been marked corrupt. Because corruption can be a serious
problem (and should be very rare), it's worth logging more detail whenever a block is added
to the corrupt replica map.
