----------------------------------

Hi Todd, i tried on 0.90.5&0.90.6, the data was lost silently. But on 0.92.0, 
the result was just same as the above 0.94.0, so this issue seems exists on 
0.90.x(or older) serials only.

> If you corrupt one of the storefiles in a region (eg using vim to muck up 
> some bytes), the region will still open, but that storefile will just be 
> ignored with a log message. We should probably not do this in general - 
> better to keep that region unassigned and force an admin to make a decision 
> to remove the bad storefile.
