That's the way it was originally.  Then the implementation of
BOOST_THROW_EXCEPTION got changed creating unexpected behavior and side
effects in all the libraries which used.  So...

Maybe we can make BOOST_HANDLE_EXCEPTION to reinstall
the initial behavior.  However this time, it should only be writable
in the SVN system by a strictly limited group of people who
know that changing the implementation of something already
in wide usage is not a good idea for lots of reasons.
