The idea is not to store POINTERS in a user space ... but to store DATA
in a user space and get a pointer to it.

why should there be a restriction on storing pointers? If you could
create your own object on the system ( another limitation of the
system ), your code would start with an object header that contains
various pointers to other data structures within the object. That type
of a structure is immediately useable in a program. Much simpler than
the alternatives available today.
