Blender.* can be shared between  scripts. I dont think globals are 
shared as in "global foobar"

I was thinking  maybe the python API could be a Fake user, would need 
some trick so it knows not no unset Objects that were originaly fake 
users on deallocations.

Tried making 1000000's pyObject-objects to  mess the user count up, 
while the databrowser displayed negative values somtimes. It didnt mess 
up the internals when saving or after the Python decrefed the variables.
