This PR attempts to add explanations on :

why exceptions that contain mutable static variables are still considered re-entrant.
why that 'assumed re-entrancy' can be challenged in a multicore environment

PS > possible improvements to this PR will be to :

add example code to demonstrate how to ensure re-entrancy in a multicore environment.

@eldruin did you forget to add this to the merge queue or are you waiting for something else to occur before doing that?

It seems to have gotten stuck somehow, repoked it, hopefully it'll get merged now. Thanks for checking in @9names!
