def _allow_new_attributes(f):

    ''''A decorator that maintains the attribute lock state of an object
    It coperates with the LockAttributesMetaclass (see bellow) that replaces
    the __setattr__ method with a custom one that checks the _canAddAttributes
    counter and allows setting new attributes only if _canAddAttributes > 0.
    New attributes can be set only from methods decorated
    with this decorator (should be only __init__ and __setstate__ normally)
    The decorator is reentrant (e.g. if from inside a decorated function another
    decorated function is invoked). Before invoking the target function it
    increments the counter (or sets it to 1). After invoking the target function
    it decrements the counter and if it\'s 0 it removed the counter.'
