Well, OK, you've just reinvented OS/360 MVT, which put all the processes in
one address space.  It's not a terrible idea if they need to communicate and
you can predict the amount of memory they'll need.  On the other hand, the
fact that MVT is long dead, replaced by MVS which allocates an address space
per process may tell us something.
