Proposal for shortcuts

[maxpoletaev]

Writing something like this:

with NonBlockingLock.objects.acquire_lock(lock_name='update_user_' + str(user.id)):
    pass

...is too hard for me.
I think we can made API more shorter and pretty. In my vision it could be function which accepts lock_name argument and returns context manager, decorator or Lock instance.

from locking import db_locking

def update_user(request):
    with db_locking.lock('update_user'):
        pass

@db_locking.lock('update_user')
def update_user(request):
    pass

def update_user(request):
    lock = db_locking.lock('update_user')
    lock.acquire()
    lock.release()

What you think?
