Date Tue, 23 Apr 2013 06:34:55 GMT
A little update:

keyspace has disappeared) works fine. No issues noticed so far.

Node A was started with larger heap and after I turned debugging on I 
can see it does this:

And it goes this way for ~10 minutes so far and it doesn't seem like 
it's going to end. I think one important thing to mention here is that 
the DRDevices CF is ~2MB large, so I guess in this time C* should be 
able to be fully rewrite it at least a few times... ;-)
