I'm not sure there is a need for a patch. I think you confuse,
something. When the script is recompiled all the variables belonging to
the package decalared by Apache::Registry or similar are getting reset. If
you require/use() some modules that declare packages and have global
variables -- these won't be reset unless reloaded or initialized in your
code.

Not if you are talking about the scripts running under Apache::Registry
and friends, please read the guide.
