Bad things can happen if you leak pointers out of RCU read-side critical sections. What can you do about it?

I looked at using an opaque wrapper for proxy guarded references that could only be used in a proxy guarded scope. I decided it wasn't worth the bother. Too verbose.

This is as far as I got.

You could add extra runtime overhead to tie the wrapped references to a specific proxy instance, I suppose.

@jwseigh I suspect that the Rust folks will eventually end up with something similar. But who knows?
