If you want to store the reference count and the shared_ptr itself in
the shared memory so that the shared_ptr is a shared_ptr between
*processes*, I'm working on a boost::shmem::shared_ptr so that you can
store a shared_ptr in shared memory (and construct containers of
shared_ptr). The reference count would be allocated also in the same
segment. Obviously, since in shared memory I have some problems(the
deleter should be a template parameter, since we can't use virtual
functions, we need a parameter to know from where to allocate the
reference count, etc...) the interface will be a bit different. But you
will need to wait a bit ;-)
