Good chunk of issues with pre-allocated exceptions (and possible 
cycles in reference counted ones) comes from the chanining 
possibility. At the same time I have yet to see it actively used 
as a feature.

Doesn't mean it is bad thing, just not used wide enough to 
compensate for trouble right now.
