How to Lock Globar Variables across Modules?

Sorry, python just doesn't work this way at the moment.  I think you
would have to change variable name lookups to check for such
'privileged' names.  That may or may not involve a lot of work.

One thing that I do to avoid having to import commonly used objects in
every module that uses them is modify the python __builtins__ module.
In main_module, you could do something like

import main_module
__builtins__.m = main_module

...and from then on, you could refer to sv as m.sv throughout your
program.  It still seems like a bad idea to me on the face of it,
though.
