That's a good question, actually. Even though in Pali's case the notifier
is atomic (so that we are pretty confident that the object won't be
unregistered), there is still a possiblity of a dead lock, for example. So
notifiers should be careful to not hold any locks, because the other
driver might call get_property(), which might acquire locks.

Thanks,

Anton
