to either use a pre-defined instance attribute as the location
of the lock, or to explicitly pass a lock object.
This code was implemented with ``threading.Lock`` in mind, but
may work with other locks, assuming that they function as
context managers.
When using ``attr``, the assumption is the first argument to
the wrapped method, is ``self`` or ``cls``.
Examples:
@lock_decorator(attr='_callback_lock')
def send_callback(...):
@lock_decorator(lock=threading.Lock())
