pythonic way to optimize access to imported value?

I don't think this is so hard:

def load_file(file, modname):
    import new
    mod = new.module(modname)
    exec open(file).read() in mod.__dict__
    return mod

Then mod should only have the one reference:

>>> import new
>>> sys.getrefcount(new.module('temp'))
1

Also see the imp module; some of the hooks there don't insert in
sys.modules (but I can't remember which ones now).

Cheers,
M.
