See #252
This is not backwards compatible (it will now hard-break), but given snappea's
rather particular design decisions this is probably for the best, and given
what else was just discovered on #252 I strongly doubt anyone was actually using
it in such setups anyway.
Stackoverflow said "In Python, everything is shared, except for function-local
variables (because each function call gets its own set of locals, and threads
are always separate function calls.) "
whatever was meant exactly by that, it's not true for us, because our functions
are called on-import, and the vars-in-closure are shared between threads. i.e.:
>>> from threading import Thread
>>> def closure():
... l = []
... def inner():
... l.append("x")
... print(len(l))
... return inner
...
>>> inner = closure()
>>> thread = Thread(target=inner)
>>> thread.start()
1
>>> thread = Thread(target=inner)
>>> thread.start()

actually: not autodiscover on-bootup, but just try to import the tasks
when you actually need them. This makes it so that we can avoid the whole
of the Django app-loading magical machinery
