Ah, I got confused by your previous points which seemed to indicate
that you wanted to somehow avoid dynamic polymorphism -- and thus the
need for memory allocation -- altogether (which is not possible.)

Other boost components, such as boost::function and boost::shared_ptr,
have an allocator parameter, so I'm assuming you're proposing
something similar. We can add a template constructor to
boost::exception that can be used to supply a custom allocator.

I'd rather not do this, but (I think) it can be implemented in a way
that wouldn't have any negative effects on users who don't want to use
the custom allocator support, so if there's demand -- why not.
