OK, so here the advantages of value vs ref types had to do "only" 
with allocation issues, and not (also) any advantages in how the 
values/objects were used per se. So, one could argue that this 
problem could also be solved through richer memory allocation 
primitives, without having to have value types?

BTW, given the GC behaviour you described, weak references 
wouldn't help, would they?
