You might ask Sean to decouple the default exception-handler from the 
runtime support in Ares. The idea would be that you could provide your 
own default-handler, and then the linker would bind that instead. Sean 
is already doing a lot of things like that with Ares, so it may not be 
too much of a stretch.
