;;;; save and restoring the dynamic environment
;;;;
;;;; These VOPs are used in the reentered function to restore the
;;;; appropriate dynamic environment. Currently we only save the
-;;;; Current-Catch and binding stack pointer. We don't need to
-;;;; save/restore the current unwind-protect, since unwind-protects
+;;;; CURRENT-CATCH and binding stack pointer. We don't need to
+;;;; save/restore the current UNWIND-PROTECT, since UNWIND-PROTECTS
;;;; are implicitly processed during unwinding. If there were any
-;;;; additional stacks, then this would be the place to restore the
+;;;; additional stacks (as e.g. there was an interpreter "eval stack"
+;;;; before sbcl-0.7.0), then this would be the place to restore the
;;;; top pointers.
