Security hole in rexec?

[Troels Therkelsen]

Thank you for your response.  While it does solve my immediate
concern, it does puzzle me that the whole thing is even possible;
__builtins__ should be read-only, but even if I make my own subclass
of dict that doesn't allow deletion of elements and pass that to exec
... in <my subclass of dict>, you can still delete it from within
exec.

Ah well.  I can live with the custom patch for now.  Perhaps
restricted execution will be solved in a more satisfactory manner
eventually :-)

Best regards,
