Yes, it switches stacks in call_into_lisp_first_time.


Could you describe the role that this stack switch plays in SBCL?
I am even more puzzled when I see in the source code that the
Win32 port seems to do away with it, staying on the original
system allocated stack, and still be a working instance of SBCL.
What does this stack manipulation buy for SBCL?
