Here's an alternative patch that does this. I tested it as far as I could,
which was running

  SCRIPT=../doc/example/00_hello/hello.pl ./test_script

in the regression/ directory. It looked fine on both Perl 5.40 and
5.42. The modglobal slot seems to have been present ever since Perl
5.005 or so.

It might still be a good idea to have somebody who actually knows Perl
internals to have a look at this. Tentatively tagging 'patch' anyway.

Hope this helps,
