It's good to see the setup of the shutdown hooks being removed from the 
initialization. However, I think it might be cleaner have each register 
itself lazily rather than SharedSecrets knowing about it. That has the 
added benefit that only the needed hooks are registered. It also avoids 
needing the reflection code. A possible downside is that each hook needs 
to know its place in the world. Attached is a (completely unpolished) 
patch that does this and perhaps it would be useful to try.
