Description: #local_mutex
        本地锁,通过fcntl针对文件加锁实现的. 需要强烈注意的是,多线程下是无效的,原因? [查看链接](http://xiaorui.cc)
        
        #Usage:
        
        最简单的例子,适合一个程序同时跑一个的场景.
        ```
        import sys
        from local_mutex import LocalMutex
        
        try:
            lock = LocalMutex('app.lock')
        except LockError:
            sys.exit('already running')
        
        try:
            print 'doing'
        finally:
            lock.release()
        ```
        
        使用wait参数不停的试图获取Lock, 直到获取锁.
        ```
        lock = LocalMutex('/var/run/app.lock', wait = True)
        try:
            print 'doing'
        finally:
            lock.release()
        ```
        
        使用with关键词
        ```
        with LocalMutex('app.lock', wait = True):
            print 'doing'
        ```
        
        如果是多线程环境,直接用threading的Lock
        ```
        import threading
        lock = threading.Lock()
        with lock:
            pass
        ```
