import and shared global variables

[Michael Brenner]

Ah, thanks everybody! I had thought that, although the name was set to 
"__main__", the module that was stored in sys.modules was m1 
nevertheless, not a copy.
Well, having to write "import m1" inside m1.py seems a bit peculiar - 
it's probably nicer to keep the "__main__" module free from stuff that 
has to be imported by others.  Would a module global.py (defining glob 
and imported by whoever needs it) be more pythonic? (I didn't want to do 
that because I really want to resist the temptation of introducing 
glob1, glob2, glob3...)
