The feature I'm only interested in is using Boost.Exception to enable my  
exceptions to be "thread-safe" without explicitly or implicitly deriving  
 from boost::exception.  It seems that to do so, at a minimum I would need:

1) boost::enable_current_exception
2) boost::rethrow_exception

Is this true?

boost::rethrow_exception requires exception_ptr and you say the latter  
requires derivation from boost::exception.  So it seems it's not possible  
to accomplish what I want using the existing Boost.Exception framework.   
If so, is it possible to add such a feature?

Thanks,

Mostafa
