So .. this is partially because we assume the stack to be zeroed 
if we have not written to it yet. It is zero-initialized after 
all, however If we are returning from a function that wrote to 
the stack and then we are calling another function, that function 
will see the state the previous function left there...

which just means ... we have to zero our temporaries and locals 
on function entery.
implementing this however breaks incremental code-generation.

Awwwww ....
