Between yours and Doug's and Paul's and Michael's examples :-) , I think 
it's pretty clear that we will want some kind of user interface. In the 
general case, a target can create arbitrarily-named address spaces, 
while in the conventional multiprogram case, address space names could 
simply be copied from exec names or process ids.
