I recall that Pascal debug builds added manual checks for stack 
overflow. This was especially necessary in real mode, where a 
stack overflow would just crash the PC. I don't see why D 
couldn't do the same. It would be useful in protected mode with 
small variables too, as it would allow generating a normal D 
exception instead of a segmentation fault.
