Description: Introduction
        ============
        
        This package provides a simple decorator to help synchronize methods across
        threads, to avoid problems of concurrent access.
        
        It can be used like this::
        
        from threading import Lock
        from plone.synchronize import synchronized
        
        class StupidStack(object):
        
        _elements = [] # not thread safe
        _lock = Lock()
        
        @synchronized(_lock)
        def push(self, item):
        self._elements.append(item)
        
        @synchronized(_lock)
        def pop(self):
        last = self._elements[-1]
        del self._elements[-1]
        return last
        
        The decorator takes care of calling lock.acquire() just before the method
        is executed, and lock.release() just after. If an exception is raised in the
        method, the lock will still be released.
