The method `maybe_wait_for_sstable_count_reduction()`, when retrieving
the list of sstables for a possible compaction, holds a reference to the
compaction strategy. If the strategy is updated during execution, it can
cause a use after free issue. To prevent this, hold a copy of the
compaction strategy so it isn’t yanked away during the method’s
execution.
