请高手帮我看看这代码是什么意思，急！！！！
public CommitLogService(final CommitLog commitLog)
    {
        queue = new LinkedBlockingQueue<Runnable>(1024 * Runtime.getRuntime().availableProcessors());
        Runnable runnable = new WrappedRunnable()
        {
            public void runMayThrow() throws Exception
            {
                while (run)
                {
                    Runnable r = queue.poll(100, TimeUnit.MILLISECONDS);
                    if (r == null)
                        continue;
                    r.run();
                    completedTaskCount++;
                }
                commitLog.sync();
            }
        };
        appendingThread = new Thread(runnable, "COMMIT-LOG-WRITER");
        appendingThread.start();        final Callable syncer = new Callable()
        {
            public Object call() throws Exception

                        Thread.sleep(DatabaseDescriptor.getCommitLogSyncPeriod());
                    }
                    catch (InterruptedException e)
                    {
                        throw new AssertionError(e);
                    }
                    catch (ExecutionException e)
                    {
                        throw new RuntimeException(e);
                    }
                }
            }
        }, "PERIODIC-COMMIT-LOG-SYNCER").start();    }
谢谢！！！！

从代码粗看，是一个借助队列来完成异步写日志的功能。循环处理的主要就是这段：
public void runMayThrow() throws Exception {
  while (run) {
    Runnable r = queue.poll(100, TimeUnit.MILLISECONDS);
    if (r == null) continue;
    r.run();
    completedTaskCount++;
  }
  commitLog.sync();
}
但信息量太少了，看不出更多信息了。
