I have nil experience with Asynqueue, but you shouldn't have to
directly interact with the reactor to start a service.

The "obvious way" depends on the application. If you're writing a
simple client application you might try something like this:
if __name__ = '__builtin__': # run with twistd -y
from twisted.application import service
application = service.Application('foo')
svc = ... # Initialize asyncqueue service
This might be more than you need for your application, but I would
suggest also reading about Twisted application plugins:

If you want a function to be called when the reactor is running, then
what you've done is correct - reactor.callWhenRunning(). However,
this is not the normal way to start services.
