Joshua McKenzie commented on CASSANDRA-8707:
--------------------------------------------

For the record - I'm vary wary of anything touching SSTableDeletingTask on 2.1 
w/regards to Windows.  That being said - changes there look fine and don't 
appear to break anything obvious to my testing over here.  Only thing that 
popped up with a mixed stress and major compaction running concurrently was 
CASSANDRA-8535 as expected.

> Move SegmentedFile, IndexSummary and BloomFilter to utilising RefCounted

> There are still a few bugs with resource management, especially around 
> SSTableReader cleanup, esp. when intermixing with compaction. This migration 
> should help. We can simultaneously "simplify" the logic in SSTableReader to 
> not track the replacement chain, only to take a new reference to each of the 
> underlying resources.
