Gary Dusbabek commented on CASSANDRA-667:
-----------------------------------------

I don't see the point of passing attempts as a param to CleanupTask.  Even if 
it were ever non-zero, the number wouldn't reflect the number of times it would 
actually be attempted. 

> Avoid causing IO contention when cleaning up compacted SSTables

> Post-CASSANDRA-408 compacted sstables are deleted in parallel, one thread per 
> sstable; this can cause IO contention with sstable flush and compaction.  
> Serialize this instead.
