My knowledge may be lacking here, but doen't pkg_resources need to
scan things beyond egg-info (to get namespace_package.txt, presumably)
Scanning egg/egg-info is easy, but that does not explain most
additional syscalls caused by pkg_resources import.

pkgutil.py implements everything needed for setuptools namespace
package ? From reading the discussions around PEP 382, it seemed much

If pkgutils.py is indeed all that is needed to support setuptools
namespace package, I am willing to look at the code to see if it can
be sped up. I really doubt that C should be used - if it takes so much
time for a couple of dozens packages, it is much more likely a design
problem than an implementation problem.
