Note that I'm currently working on a variation of the patch that implemen=
ts a
subset of iu.py (I think I mentioned this a few times already ;-). For ea=
ch path
item, each item in a list of hooks is asked whether it can handle the pat=
h item;
the first one that can is used. This is done *once* per path item, the re=
sults
are cached in a dict (iu's shadowpath): {path_item: path_handler, ...}. T=
his
gives the zipimporter a chance no matter what the extension is and it's s=
till
cheap as it's only done once.
