Do directory mtimes get recursively updated? I don't think they do.
So if you have a layout:
site-packages/
zope/
interface/
__init__.py
And you update the package and update __init__.py, the mtime of
site-packages doesn't change, does it?
I'm saying if there was a file in site-packages/last_updated that gets
touched everytime an installer does anything in site-packages, then
you could cache (between processes) the lookups.
