I'd definitely call it code smell. What happens with this?
with lock:
def inner():
do_more_work()
f.add_done_callback(inner)
The lock's possibly released before the callback happens, or possibly
not, but either way, the code *looks* as if it's all happening inside
the "with lock" block. Recipe for confusion IMO.
