Hm. I didn't try it with two {}'s. Why shouldn't one work? Shouldn't it
just use the same for globals and locals?

This "works"
 >>> xdict={}
 >>> execfile('executable.py',xdict)
 it's me
 init
 >>> xdict.clear()
 deleted

but xdict going out of scope doesn't do it
and neither does del xdict. Shouldn't they?
