[Mono-list] I must misunderstand delegates

Sorry, I did a really fantastic job of typing that last bit of code :) What
I meant follows...
> One more (pedantic) thing, if your events are intended to be thread-safe,
> they shouldn't be fired as you have done above.
> The problem is that between your null-check and the invocation the
> subscribers could unsubscribe from another thread, and you'll get a
> NullReferenceException thrown at the invocation.
> This can be avoided by doing something like this:
> AgeChangeHandler ageChange = ageChange;
> if (ageChange != null)
AgeChangeHandler ageChange = _ageChange;
if (ageChange != null)
