> {{SegmentedRaftLog.close() may deadlock with the background cache eviction thread.}}
> Currently, close() acquires the Raft log write lock before calling cacheEviction.close(). 
> That method interrupts the eviction thread and waits for it to terminate using Thread.join().
> {{Meanwhile, checkAndEvictCache() also needs the same write lock.}}
