The imp module and cyclic imports

Thanks for the hint. You're right. This isn't actually imp related. The
standard import also fails.

Unfortunately, this fails if one.py and two.py are in different
directories/packages.
With a setup like
web1/one.py
web2/two.py
there doesn't seem to be any way to make one.py and two.py reference
each other via (non-delayed) imports.

It's interesting, though, that cyclic imports work when using the plain
"import foo" import, but not with the "from package import foo" style.
Especially since the former also used to fail (google for "python
cyclic imports" on groups.google.com). I wonder whether the "from"
style imports were overlooked when the cyclic problem was fixed.
