IIUC, while the custom allocators let you put std::containers in shared 
memory they are still not very useful since they can only be used by 
the process that put them there - other processes will (potentially) 
see the shared memory at a different address and all the pointers will 
be wrong.  Is this level of functionality useful to you?
