> The reloading of the compaction strategy done during CFS.reload is not thread
> safe. In particular, this is a problem for leveled compactions. It could
> leads to some sstable not being added to the manifest and also breaks the
> 'only one leveledCompactionTask can run at any given time' assumption (which,
> at least without CASSANDRA-3408 can likely leads to blocking compactions
> completely).
