Also, ask Terry Dunbar.  The TLD compiler used for some of the
communication satellite software on a 1750A required a code
sharing model.  There is a consequent trade-off between time and
memory.  On a 1750A, there is little of either, but certainly more
of time than memory.   Yes, I know about the MMU, but the MMU cannot
be used on most satellites.  Takes too much real-estate and draws
too much power.  

I wonder what kind of model Terry will use for Ada 95.  I heard he would use
GNAT, but that would run counter to the model of his Ada 83 design.  Anyone
heard from Terry lately?
