The sparc version of the c++ interpreter does cutback and deals with the 
window area, template could too. Although the truth be told back in the 
last millenium when I did the initial implementation of the c++ 
interpreter on sparc I had it cut back the stack because I mistakenly 
thought that the template interpreter did it that way and I wanted it to 
use similar amounts of stack space. :-)
