Importing adds a whole lot of nodes

[asl97]

Importing anything that hasn't been imported before (ie: not in sys.modules, eg: the html module*) seem to add a whole lot of nodes.

I had to manually whitelist names for it to produce what I expected.

Manually whitelisting is troublesome to say the least.

* on my system, it wasn't imported when I start a python shell

empty1.py

import empty2

def hello():
    pass

empty2.hello()

hello()

empty2.py

def hello():
    pass

pycallgraph graphviz -- /tmp/junk/empty1.py:

pycallgraph -i '__main__' -i 'hello' -i '<module>' -i 'empty2*' graphviz -- /tmp/junk/empty1.py

Same for me

-e/--exclude option doesn't work at all for me.
I still see these unknown/unnamed nodes
