Yes, you are right: I created a main loop, called run(), and the
callback got called.
Anyway, I don't understand why is not possible to ensure that the end
callback gets called even without a main loop :?
Thanks!

Without actually modifying the code (i.e. I'm doing this off the top of
my head), that should work.
