Yes you are right. I didn't look at your patch closely enough to
see that you were going to do symbol lookups during the notification.

I don't want to force you to take any approach. A signal at symbol
file update is good too. However, could you in that case use a different
name for the observer, I found it confusing since the notification is not
necessarily emitted when the program has been changed. Something like
program_symbols_changed?

We'll have two observers instead of one: One for the executable changed,
and one for the program symbols changed.

I don't know what the other maintainers will think about this?
