Don't know if I get that right. My real world objects constructs just 
fine when I make  the constructor
public.  The only problem I have  is that:

<snip>
 segment.find_or_construct<Foo>("FooObject")(alloc);
</snip>

complains that my constructor is private:
within this context:

<snip>
#    if BOOST_PP_LOCAL_C(1)
        BOOST_PP_LOCAL_MACRO(1)
#    endif
</snip>

which isn't very helpful. I already tried to make
class managed_shared_memory a friend. But
since managed_shared_memory is just a typedef
from basic_shared_memory<...> that doesn't work
either.

Thanks again
