> Leakage of references to SSTable on unsuccessful operations

> This is a little bit tricky to describe correctly as I can talk about the
> symptoms only. I hit this issue when testing CASSANDRA-18781.
> In a nutshell, when we go to bulkload an SSTable, it opens it in
> SSTableLoader. If bulkloading fails on server side and exception is
> propagated to the client, on releasing of references, it fails on this assert
> (1). This practically means that we are leaking resources as something still
> references that SSTable but it was not tidied up (on failure). On a happy
> path, it is all de-referenced correctly.
> I think that this might have implications beyond SSTable loading, e.g. this
> could happen upon streaming too.
