>
> TestLazyPersistFiles#testLazyPersistBlocksAreSaved verifies that the memory 
> block is saved in lazy persist directory after some sleep with the following 
> code. 
> {code}
>     // Sleep for a short time to allow the lazy writer thread to do its job
>     Thread.sleep(6 * LAZY_WRITER_INTERVAL_SEC * 1000);
> {code} 
> However, the sleep only guarantees an async lazy persist task is scheduled. 
> The task running on a per volume thread pool thread can take longer to finish 
> persisting. It will be more deterministic to wait the pending lazy persist 
> task count reduce to 0 before verifying the block file exist in lazy persist 
> dir.
