Hmmm, I thought one had to be careful using ihooks going forward. I
thought:
http://www.python.org/dev/peps/pep-0302/
defined proper way of doing things now. The PEP says:
Forward Compatibility
Existing __import__ hooks will not invoke new-style hooks by
magic,
unless they call the original __import__ function as a fallback.
For example, ihooks.py, iu.py and imputil.py are in this sense not
forward compatible with this PEP.
I haven't got source code for Python to look at at moment to work it
out.
