Scoped Lock

[Sean R. Lynch]

How about:

def lock_call(mutex, func, *args, **kwargs):
     mutex.acquire()
     try:
         res = func(*args, **kwargs)
     finally:
         mutex.release()

     return res

def do_something(blah):
     # do stuff

m = threading.Lock
lock_call(m, do_something, "some data")
