-Subject: [PATCH 1/4] Sanitize op stack for error conditions
-
-We save the stacks to an array and store the array for the error handler to
-access.
-
-For SAFER, we traverse the array, and deep copy any op arrays (procedures). As
-we make these copies, we check for operators that do *not* exist in systemdict,
-when we find one, we replace the operator with a name object (of the form
-"/--opname--").
