+;;; Test case for unwinding an alien (Win32) exception frame
+;;;
+;;; The basic theory here is that failing to honor a win32
+;;; exception frame during stack unwinding breaks the chain.
+;;; "And if / You don't love me now / You will never love me
+;;; again / I can still hear you saying / You would never break
+;;; the chain."  If the chain is broken and another exception
+;;; occurs (such as an error trap caused by an OBJECT-NOT-TYPE
+;;; error), the system will kill our process.  No mercy, no
+;;; appeal. So, to check that we have done our job properly, we
+;;; need some way to put an exception frame on the stack and then
+;;; unwind through it, then trigger another exception.  (FUNCALL
+;;; 0) will suffice for the latter, and a simple test shows that
+;;; CallWindowProc() establishes a frame and calls a function
+;;; passed to it as an argument.
