I don't know much about this, but it seems to me that a machine without
register windows is oiggoing to have to put those values on the stack
in any case.  A machine with lots of registers that have to be stored
and loaded in deep recursion should at least be able to take advantage
of any burst mode that the memory subsystem supports, thus giving an
advantage over normal architectures.
